Ghoulcaller Gisa asks you to spend five mana on a creature that usually has to survive a trip around the table before doing her thing. That’s the first place I’d look for a Wretched Ranks upgrade. Once she can tap, one black mana and another creature turn into a pile of Zombies. Getting that first activation, then having something worthwhile to feed her, seems more useful than adding another expensive payoff.

Wretched Ranks is the mono-black Foundations Commander precon released October 2. Wizards’ confirmed decklist has 39 lands and plenty of creatures that reward a growing Zombie army. The early Foundations overview introduced Gisa before the full lists were public. With the actual hundred available, I’d try four changes and keep the mana base intact.

The reference additions below total $10.52 before shipping. That assumes you buy all four, which I’d avoid doing until you’ve searched the collection. One spare piece of Equipment can make a fairly large difference to how this commander feels.

Four Wretched Ranks upgrade swaps

These cuts start from the unmodified deck. Prices are Scryfall USD snapshots checked October 23, 2026, for the exact non-foil additions linked here. Outgoing links show the Foundations Commander copies.

Take out Put in What I’d try to improve Reference price
Commander’s Sphere Patriar’s Seal Keep a three-mana rock and gain a way to untap Gisa $4.06
Marchesa’s Decree Swiftfoot Boots Give Gisa haste and protection from opposing targeted effects $1.76
Moan of the Unhallowed Jadar, Ghoulcaller of Nephalia Establish a recurring source of sacrifice fodder earlier $1.56
Soulless One Rotting Regisaur Get seven power for Gisa from a three-mana creature $3.14

None of these additions is in the stock list. All four are currently legal in Commander and fit Gisa’s mono-black color identity. Four cards leave, four enter, and the deck stays at 100 with the same 39 lands.

I’d start with the Boots and Seal if you have spare copies. If you only find Jadar, try that single swap first. There’s no reward for completing the whole table before playing again.

Gisa needs to be ready, and the black mana needs to stay open

Swiftfoot Boots costs two to cast and one to equip. The equipped creature has haste and hexproof. Haste lets a newly cast Gisa activate her tap ability; hexproof still lets you target her with your own spells and abilities, including the Seal.

With the Boots already on the battlefield, casting Gisa, equipping her, and activating once costs seven mana: five for Gisa, one to equip, one black for the activation. You also need another creature to sacrifice. If you use every available mana casting the commander, the Boots won’t manufacture the missing black for you.

Equip normally happens at sorcery speed. Opponents can respond before the equip ability resolves, and hexproof won’t save Gisa from a board wipe. I’d still rather ask them to answer her before she starts producing tokens than give them everyone’s turn to find removal.

Marchesa’s Decree is a painful cut. It makes you the monarch when it enters, which can supply a card at your end step while you hold that title. Its attack trigger also charges opponents a life for each creature attacking you or your planeswalkers. Losing that repeatable draw can hurt. I’m favoring earlier access to the commander’s ability, but if Gisa already survives comfortably and your hand keeps emptying, I’d put the Decree back before searching for a fifth upgrade.

Patriar’s Seal costs three and taps for one mana of any color. Its other ability costs one mana and a tap to untap a legendary creature you control. Gisa qualifies. The artifact can use that ability on the turn it enters, provided you can pay for it.

Suppose Gisa is ready and you have one ordinary 2/2 Zombie token, with no bonuses affecting power. Pay a black, tap Gisa, sacrifice it, and make two 2/2s. Pay one and tap the Seal to untap her. Pay another black, tap Gisa again, and sacrifice one of those new tokens. You finish with three 2/2 Zombies. The sequence spent three mana, used the Seal, and left Gisa tapped again.

You can’t tap the Seal for mana and also tap it to untap Gisa without another effect untapping the artifact. The outgoing Sphere could be sacrificed to draw a card; the Seal gives up that escape hatch. On turns where you need every mana source to cast something, it can simply work as a mana rock.

Patriar's Seal from Commander Legends: Battle for Baldur's Gate, a mana rock that can untap Ghoulcaller Gisa

If you already own Thousand-Year Elixir, I’d test it before buying another untap effect. It lets you activate creatures’ abilities as though they had haste and has its own one-mana tap ability to untap a creature. It won’t make Gisa able to attack immediately, and it won’t replace the Seal’s mana production. Keep the slot’s job in mind when choosing which card leaves.

Seven power is a lot of bodies

Rotting Regisaur is a 7/6 Zombie Dinosaur for two generic and one black. Sacrifice it to Gisa without any power modifiers and you get seven 2/2 Zombies. That’s a substantial battlefield from one activation, assuming Gisa and the Dinosaur both make it far enough to do the work.

The existing Death Baron gives your other Zombies +1/+1 and deathtouch. Beside it, Regisaur has eight power when sacrificed, so Gisa makes eight tokens. Those tokens receive the Baron’s bonus too. Gisa herself is a Human Wizard and gets no Zombie bonus from the Baron.

Regisaur also makes you discard a card at the beginning of your upkeep. With an empty hand, you have nothing to discard. With a useful spell still in hand, you can lose something you’d rather have kept. If Gisa is ready and you can pay, you can sacrifice the Dinosaur before your next upkeep begins. Sacrificing it after the discard trigger has gone on the stack won’t remove that trigger.

Soulless One can be much larger in a long game. It counts Zombies across the battlefield and Zombie cards in every graveyard, so I’m giving up a potentially enormous creature to get predictable power a mana earlier. I don’t know how often your table gives you time to make the Avatar ridiculous. Against other creature decks, this might be the swap you reverse first.

I spent a Core Set 2020 prerelease calling Regisaur “Regisaurus” and wrote it that way on a little trade list. A kid corrected the spelling, then asked whether the rest of the list was real. Fair question. The handwriting was doing none of those cards any favors either.

Jadar is the smaller, steadier addition. At the beginning of your end step, if you control no creatures with decayed, he creates a 2/2 Zombie with decayed. That token can’t block, and attacking with it causes it to be sacrificed at end of combat. Gisa can sacrifice it without sending it into combat at all.

Consume the decayed token before your end step begins if you want Jadar to replace it that turn. Gisa’s ordinary Zombie tokens don’t have decayed, so they won’t prevent the next Jadar token. Without other power changes, exchanging Jadar’s 2/2 for two ordinary 2/2s gives you bodies that can block.

Moan supplies two Zombies immediately for four mana and can be cast again through its seven-mana flashback cost. Jadar needs end steps and has to survive. If the table removes him before that first end step, you’ve received no tokens. I’d try the cheaper recurring creature, especially when it can establish fodder before Gisa arrives, while keeping Moan with the removed cards.

Check the cards in the box before ordering anything

Gravecrawler already comes in Wretched Ranks. With another Zombie under your control after you sacrifice it, you can cast it from the graveyard again. That’s useful existing fodder for Gisa. Adding a second copy to the same Commander list won’t help, so leave it off the shopping list.

Okay, Gisa’s untapped. You’ve got a creature. A whole plan. Where’s the black mana? Ah. You spent it casting the other thing. Leave a Swamp up next time. This deck can make its own turns look finished while the most useful activation is still waiting for a payment.

Search the four additions by name in Eldwyn or your existing inventory, then check where each physical copy lives. A pair of Boots committed to another commander needs a decision before it moves. The want-list check against your collection covers that gap between an owned count and an available card.

Preconstructed Commander decks recorded in Eldwyn, shown as an example of keeping deck contents organized

Record each incoming printing and keep its outgoing card labeled with the original deck. The precon upgrade tracking guide explains how to preserve the stock list alongside the version you’re playing. Older printings work; the table’s editions identify the price snapshots, rather than a requirement to find those exact copies.

After a few games, I’d want three short notes: whether Gisa activated before being removed, whether the Seal bought a useful second activation, and whether Regisaur ate a card you needed. If Jadar kept leaving you a creature while Gisa was unavailable, keep him. If the monarch draw was the thing you missed most, there’s a four-mana enchantment waiting in the removed pile.
