Redcoat Squirrel

Flash

Dash {2}{r} (You may cast this spell for its dash cost.
If you do, it gains haste, and it's returned from the
battlefield to its owner's hand at the beginning of the
next end step.)

Whenever Redcoat Squirrel enters or attacks, put a
+1/+1 counter on target creature. That creature
gains first strike until end of turn.
