Clever Concealment

Phasing has always been one of Magic's quieter keywords, a permanent that vanishes without dying: no death triggers, no re-entering the battlefield, no summoning sickness on the way back. This scales that trick to the entire board. Any number of your nonland permanents wink out until your next turn, which turns the mechanic into a full-team fog against an alpha strike, a way to dodge a sweeper, or a means to hold your creatures clear of a Cyclonic Rift or an edict. The elegance is that phased-out permanents return exactly as they left: tapped stays tapped, Auras and counters ride along, and nothing that keyed off a departure ever fires. Convoke answers the affordability question, since the same board you want to save contributes to saving itself: a token army can pay most of this cost. That is the built-in tension. It wants a lot of bodies to be cheap, and it protects best when there are exactly that many bodies to protect, so both halves scale off one board state. Being an instant is what lets the plan cohere, but the timing is unforgiving: to protect against a wrath you must cast this before that wrath resolves, because once it finishes your permanents are already gone. You hold the spell until attackers are declared and blocks loom, or until a sweeper is announced, and only then spend the board to save the board.
