mtg banned modern cards The Commander Ban List: All 83 in EDH list of banned cards mtg

Essentially, if you have a full party with all four of these on the board, you can pay one white, one blue, and one black mana to give the Warrior lifelink, deathtouch, and make him unblockable (deathtouch and unblockable at the same time has no real use, but thats still OP to think about)

If it's a nonland card, create a 2/2 black Rogue creature token

You see it reads, Create X 2/2 black Zombie creature tokens with decayed, where X is half the number of creature cards in your graveyard, rounded up. Tokens that you can sacrifice or simply swing in with are going to be a huge help in most Golgari decks, so this should do well

As for removal, this archetype can borrow the red-green archetype's fight and bite cards to take advantage of its tough enchanted creatures or borrow tap-based effects from white-blue if necessary
