Deathtouch (Any amount of damage this deals to a creature is enough to destroy it.)
, Sacrifice another creature: You gain life equal to the sacrificed creature's toughness.
, Sacrifice another creature: Exile target nonland permanent. Activate only if you have at least 10 life more than your starting life total.
Ayli is a sacrifice engine that converts your creatures into life and targeted removal. You build a board, fuel Ayli's first ability to gain life and trigger payoffs, then use the second ability to exile any problematic nonland permanent once you're above 50 life. The deck grinds value through aristocrats synergies before assembling a combo or simply outvaluing the table.
Repeatable, unconditional exile removal hits commanders, planeswalkers, and indestructible threats
Cheap two-mana commander that's hard to answer permanently and easy to recast
Life gain enables a whole package of payoffs and keeps you out of burn/aggro range
Deathtouch makes Ayli a strong blocker and deters attacks
BW gives access to the best tutors, reanimation, and recursion in the format
Exile ability is gated behind a 10-life threshold, slow to come online without payoffs
Needs a steady stream of creatures to sacrifice, vulnerable to board wipes
Relatively low ceiling without combo support; can durdle on raw value
Sacrifice loops require multiple pieces, making the deck assembly-dependent
Color identity lacks card draw and ramp compared to other pairings
