Talon Gates of Madara

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.

Phasing out doesn't cause any "leaves the battlefield" abilities to trigger. Similarly, phasing in won't cause any "enters the battlefield" abilities to trigger.

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 during that turn, and their activated abilities with {T} in their costs can be activated. If a permanent had counters on it when it phased out, it will have those counters when it phases back in.

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.

When you activate Talon Gates of Madara's last ability, you must reveal Talon Gates of Madara from your hand until that ability resolves or otherwise leaves the stack. If Talon Gates of Madara isn't still in your hand as that ability resolves, nothing happens.
