Kathril, Aspect Warper
Legendary Creature — Nightmare Insect
When Kathril, Aspect Warper enters the battlefield, put a flying counter on any creature you control if a creature card in your graveyard has flying. Repeat this process for first strike, double strike, deathtouch, hexproof, indestructible, lifelink, menace, reach, trample, and vigilance. Then put a +1/+1 counter on Kathril for each counter put on a creature this way.

裁定
For each applicable keyword, the appropriate counter may be put on any creature you control, including Kathril. The counters don’t need to all be put on the same creature.
You check once for each keyword. If you have two creature cards with flying in your graveyard, you put just one flying counter on a creature you control, not two.
Once Kathril’s ability begins resolving, no player may take other actions until it’s done and you’ve put +1/+1 counters on Kathril.
