The Lost Caverns of Ixalan

When Armored Kincaller enters the battlefield, you may reveal a Dinosaur card from your hand. If you do or if you control another Dinosaur, you gain 3 life.

Whether or not you control another Dinosaur is checked only as Armored Kincaller's ability is resolving. It doesn't matter if you still control Armored Kincaller at the time, or if it's still a Dinosaur.
