Undercity Eliminator puts a repeatable exile-removal engine on board — pay mana, sacrifice a creature, exile a target creature or planeswalker, no questions asked. The cost is real: you're feeding your own board to run opponents' threats out of the game permanently. In Altaïr Ibn-La'Ahad decks specifically, that cost becomes an engine, turning every sacrifice into a stacked trigger chain.

Altaïr Ibn-La'Ahad
Altaïr Ibn-La'Ahad rewards you for marking and eliminating targets, and Undercity Eliminator is one of the cleanest outlets — sacrifice a token, exile a marked creature, and let Altaïr's ability stack up experience counters and buffs across the board.

Undercity Eliminator is a Commander card, full stop — the sacrifice-to-exile clause scales best when you have a steady token supply or creatures you want to sacrifice anyway, both conditions that Commander's slower pace and creature-dense tables reward. In 60-card formats like Modern and Pioneer, three mana for a 3/3 that requires additional investment to remove a single threat is too slow against leaner, more consistent removal suites. Legacy and Vintage have no interest in it for the same reason — efficiency floors are too high. Standard is its only competitive-adjacent home, and even there it's a fringe roleplayer rather than a staple.

Price Context
Current price
$0.22 bulk tier
At $0.22, Undercity Eliminator is deep bulk — pick it up without thinking twice if you need it. Bulk rares at this price point rarely climb unless they find a breakout format home, and Undercity Eliminator's niche is narrow enough that the floor is likely where it stays.
