Perch Protection

Any creatures that phase in under your control as your next untap step begins will be able to attack and pay a cost of {T} during that turn.

If a player has protection from everything, it means three things: 1) All damage that would be dealt to that player is prevented. 2) Auras can't be attached to that player. 3) That player can't be the target of spells or abilities.

Permanents that phase out with counters phase in with those counters.

For instants and sorceries with gift, the gift is given to the appropriate opponent as part of the resolution of the spell. This happens before any of the spell's other effects would take place.

If a token is phased out, it will phase in as your next untap step begins.

If your life total can't change and an effect would set your life total to a specific number that's different from your current life total, that part of the effect won't do anything. Similarly, if an effect would cause you to exchange life totals with another player, the exchange won't happen, and neither player's life total will change.
