Gyrana, the Essencespeaker

Companion — Each creature card in your
starting deck has flying, first strike, deathtouch, hexproof, lifelink, menace, reach, trample, or vigilance. (If this card is your chosen companion,
you may cast it once from outside the game.)
Whenever you cast a creature spell, put a flying counter on a creature you control if that spell has flying. Repeat this process for first strike, deathtouch, hexproof, lifelink, menace, reach, trample, and vigilance.
