Text (ON): 3/2. ; Tap two untapped Beasts you control: Target creature gains first strike until end of turn.
Since the ability does not have the {Tap} symbol, you can use the ability before this creature begins a turn under your control. [Onslaught FAQ 2002/09/24]
It can tap itself but is not required to do so. [D'Angelo 2002/10/15]
