Unite the Coalition

If Unite the Coalition is copied, the effect that creates the copy may allow you to choose new targets, but you can’t choose new modes.

Phased-out permanents are treated as though they don’t exist. They can’t be the targets of spells or abilities, their static abilities have no effect on the game, their triggered abilities can’t trigger, they can’t attack or block, and so on.

If you choose any mode more than once, you choose the relative order of each of those modes.

An attacking or blocking creature that phases out is removed from combat.

Choices made for permanents as they entered the battlefield are remembered when they phase in.

Permanents phase back in during their controller’s untap step, immediately before that player untaps their permanents. Creatures that phase in this way are able to attack and pay a cost of {T} during that turn. If a permanent had counters on it when it phased out, it will have those counters when it phases back in.

No matter which combination of modes you choose, you always follow the instructions in the order they are written.
