Vaultborn Tyrant

When the token copy of Vaultborn Tyrant enters the battlefield, its second ability will trigger.

If Vaultborn Tyrant was copying something else when it was last on the battlefield but somehow still had its last ability, then the token enters the battlefield as whatever Vaultborn Tyrant copied, with the listed exceptions.

If one or more static abilities that apply to a creature entering the battlefield change its power, those abilities are considered when determining whether or not Vaultborn Tyrant’s second ability triggers. The same is true for replacement effects that apply to it, such as entering the battlefield with one or more +1/+1 counters or entering the battlefield as a copy of another creature.
