suis-je affecté par Winter Orb lorsque je dégage mes terrains?
Oui.
Citation :
Vu que la Winter Orb repasse en phase au même moment que je dégage mes permanents
En réalité non. Durant l'untap, la première chose à faire c'est gérer les permanent qui phase in et phase out. Seulement une fois cela fait on détermine les permanents qui doivent se dégager et on les dégage.
502. Untap Step
502.1 First, all phased-in permanents with phasing that the active player controls phase out, and all phased-out permanents that the active player controlled when they phased out phase in. This all happens simultaneously. This turn-based action doesn't use the stack. see rule 702.25, "Phasing."
502.2 Second, the active player determines which permanents they control will untap. Then they untap them all simultaneously. This turn-based action doesn't use the stack. Normally, all of a player's permanents untap, but effects can keep one or more of a player's permanents from untapping.
502.3 No player receives priority during the untap step, so no spells can be cast or resolve and no abilities can be activated or resolve. Any ability that triggers during this step will be held until the next time a player would receive priority, which is usually during the upkeep step. (see rule 503, "Upkeep Step.")
