Trample (This creature can deal excess combat damage to the player or planeswalker it's attacking.)
Whenever you attack, choose one —
• Create a tapped and attacking X/X green Dinosaur creature token with
trample (This creature can deal excess combat damage to the player or planeswalker it's attacking.), where X is the greatest power among other attacking creatures.
• Create X 1/1 white Vampire creature tokens with
lifelink (Damage dealt by the creature also causes its controller to gain that much life.), where X is the number of other attacking creatures.
