Snapping Turtle

Snapping Turtle gets -1/+1 when it is not your turn.
{1}: Snapping Turtle gets -3/+3 until end of turn. You may kick this ability for {2}; if you do, Snapping Turtle gets -2/+6 until end of turn instead. Either way, activate this ability only once per turn.
{u}{u}{u}: Snapping Turtle gains hexproof until end of turn.
I like turtles.
