Riverfall Mimic

Creature — Shapeshifter    (CMC:2)

Whenever you cast a spell that's both blue and red, Riverfall Mimic has base power and toughness 3/3 until end of turn and can't be blocked this turn.

Mimics don't hide their natural form well, but their disguises work well enough on boggarts.

The ability triggers whenever you cast a spell that's both of its listed colors. It doesn't matter whether that spell also happens to be any other colors.
8/1/2008
If you cast a spell that's the two appropriate colors for the second time in a turn, the ability triggers again. The Mimic will once again become the power and toughness stated in its ability, which could overwrite power- and toughness-setting effects that have been applied to it in the meantime.
8/1/2008
Any other abilities the Mimic may have gained are not affected.
10/1/2009
The effect from the ability overwrites other effects that set power and/or toughness if and only if those effects existed before the ability resolved. It will not overwrite effects that modify power or toughness (whether from a static ability, counters, or a resolved spell or ability), nor will it overwrite effects that set power and toughness which come into existence after the ability resolves. Effects that switch the creature's power and toughness are always applied after any other power or toughness changing effects, including this one, regardless of the order in which they are created.
