Territorial Allosaurus

The kicker ability doesn't let you pay a kicker cost more than once.

To determine a spell's total cost, start with the mana cost (or an alternative cost if another card's effect allows you to pay one instead), add any cost increases (such as kicker), then apply any cost reductions. The spell's mana value remains unchanged, no matter what the total cost to cast it was.

If a card or token enters as a copy of a permanent, the new permanent isn't kicked, even if the original was.

If a spell's kicker cost was paid, the spell is "kicked."

If you copy a kicked spell on the stack, the copy is also kicked. If the copied spell is a permanent spell, the token the copy of that spell becomes when it enters is also kicked.

If you put a permanent with a kicker ability onto the battlefield without casting it, you can't kick it.

Territorial Allosaurus's ability can target another creature you control (such as a Dinosaur with an enrage ability). If you kicked it but your opponent controls no creatures that are legal targets, the ability must target another one of your creatures. Plan carefully before kicking Dinosaurs.

If Territorial Allosaurus isn't on the battlefield as its triggered ability resolves, or if the target of that ability is illegal, no creature will deal or be dealt damage.
