Zethi, Arcane Blademaster copies any instant imprinted on it whenever it attacks; with Teferi's Protection exiled under Zethi, each attack pays 2W to put the table on ice — permanents phase out through every opponent's turn and come back ready to attack again. The lock is self-sustaining as long as Zethi survives to declare an attack each turn, so a haste enabler or summoning sickness removal matters on the first pass.
Recipe
How it works
01
Prerequisites
—
02
Steps
- Declare Zethi as an attacker, triggering its ability, copying Teferi's Protection and causing you to pay
to cast the copy from exile.
- Resolve the Teferi's Protection copy, causing your life total to be unable to change until your next turn and causing all permanents you control to phase out.
- Repeat during each of your turns.
03
Result
Permanents you control phase out during your opponents' turns; Your life total can't change during your opponents' turns; Lock
Variations
Cheaper, tighter, alternate lines
The lock demands a kill condition on top — Zethi's attacking anyway, so pair it with a second imprinted instant like Swords to Plowshares or Chaos Warp to answer threats while the board is still visible. Counterspell backup on the stack protects the first Teferi's Protection copy from disruption before the loop closes; after the first resolution, phased-out permanents are untargetable and the lock holds itself.
