Instant, 2{G/U} (3) Target creature loses all abilities and becomes a 1/1 green Snake until end of turn. Draw a card. Losing his possessions distressed him, but the lack of limbs was strangely liberating.

8/1/2008: Snakeform overwrites most other effects that change or set the targeted creature's power and toughness. But certain other effects can still apply to it afterward. They are: -- Effects that happen after Snakeform resolves that change the creature's power or toughness (like Giant Growth) or set its power and toughness to certain values (like Lignify). -- Counters that change the creature's power and toughness, such as +1/+1 or -1/-1 counters, regardless of when they were put on that creature. -- Static abilities that change the creature's power and toughness (such as those from Glorious Anthem), regardless of when they first took effect. -- Effects that switch the creature's power and toughness, regardless of when they first took effect.
8/1/2008: Snakeform doesn't counter abilities that have already triggered or been played. In particular, there is no way to play this to stop a creature's "At the beginning of your upkeep" or "When this creature comes into play" abilities from triggering.
8/1/2008: If the affected creature gains an ability after Snakeform resolves, it will keep that ability.
8/1/2008: If Snakeform affects a creature with changeling, the creature will lose its changeling ability, and will no longer be all creature types.
