, Reveal this card from your hand: Put a prey counter on target creature. Activate only during your turn.
When Tetzimoc enters, destroy each creature your opponents control with a prey counter on it.
Tetzimoc is a mono-black control commander that picks off threats before he even hits the battlefield. From your opening hand you spend each turn to mark opposing creatures with prey counters, then cast Tetzimoc as a one-sided board wipe that also leaves a 6/6 deathtouch body behind. You grind the game out with removal, recursion, and card advantage before closing with a big finisher or commander damage.
Repeatable, targeted board wipes—recast Tetzimoc to mark and destroy threats again
6/6 deathtouch is a strong defensive blocker and beater that profits from removal
Mono-black gives access to the best tutors, ramp, and recursion in the format
Prey counters can be seeded for free from hand, dodging counterspells on the kill
Marking creatures requires Tetzimoc in hand, telegraphing the wipe and giving opponents time to react
No card draw or evasion built in—relies entirely on the 99
Mono-black struggles with enchantments and is weak to graveyard hate on its recursion package
Slow tempo: each prey counter is one mana per creature, easily outpaced by go-wide decks
