Fate Transfer

Counters are usually a one-way street: once a +1/+1 lands on a creature it stays there, once a -1/-1 starts shrinking something it keeps shrinking. This breaks that assumption for two mana at instant speed, treating every counter on a body as a movable resource rather than a permanent feature. The "move all" clause is what makes it strange to evaluate, because it ignores the sign entirely. A creature loaded with +1/+1 counters can have its bulk relocated onto a token you control; a creature dying under a pile of -1/-1 counters can hand that liability to something the opponent is relying on. It even touches counters that have nothing to do with stats: loyalty-style markers, keyword counters, charge counters on the rare creature that carries them. The instant-speed window is the load-bearing part. Wait until blockers are declared, until a -1/-1 trigger has resolved, until your opponent has committed to a board built around a single buffed threat, then redirect everything in response. The design problem it answers is symmetry: counters are color-pie neutral and accumulate on both sides of the board, so giving blue-black a clean way to reassign them turns an opponent's investment into yours without paying for the counters yourself. It does nothing in a deck with no counters flying around, which is exactly the constraint that pins it to a build-around rather than a maindeck staple.
