Gatherer Card Rulings [Nov 2009]

• 10/1/2007: The value of X is determined when the ability resolves. It won't change later, even if the number of Elves you control changes.
• 10/1/2007: If you control no Elves when the ability resolves, the Forest will become a 0/0 creature and be put into the graveyard. However, since Elvish Branchbender is itself an Elf, the Forest will usually be at least a 1/1.
• 8/1/2008: A noncreature permanent that turns into a creature is subject to the "summoning sickness" rule: It can only attack, and its {T} abilities can only be activated, if its controller has continuously controlled that permanent since the beginning of his or her most recent turn.
