Eventide's Shadow

Black's card-draw has always been priced in life, but the meter here reads counters instead of cards drawn against your remaining total. The effect turns the entire battlefield's counter economy into a resource pool: every +1/+1 on an opponent's creature, every loyalty counter on a planeswalker, every charge or oil counter feeding some engine becomes a card you can convert to your hand at one life apiece. That dual role is what makes it strange to build around. It is simultaneously a draw spell whose ceiling scales with the game state and a removal-adjacent tool that can shrink a counter-pumped army, defang a planeswalker by stripping its loyalty, or peel a shield counter off a protected threat, all in a single sorcery. The symmetry cuts both ways: because it removes counters from among permanents rather than opponents' permanents, your own accumulated counters are fair fuel too, which lets a deck that deliberately grows its board overdraw when it chooses. The life loss is the governor: unlike a fixed-payment draw spell, this one hands you the throttle and dares you to pull exactly the counters that hurt an opponent most while paying only for what you take. The one hard limit is that the spell reads nothing off an empty board; its floor is a dead card into a table that happens to be running no counters at all, which ties its value entirely to what the game around it has already built.
