增幅（你施放此咒語時可以額外支付。）
當據地異特龍進戰場時，若它已增幅，則它與另一個目標生物互鬥。

Rulings:

• 4/27/2018 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.
• 4/27/2018 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.
