Yoldir, the Enduring Flame

If a creature you control would get +X/+X until
end of turn, instead put X +1/+1 counters on it.
If a creature you control would gain first strike
until end of turn, instead put a first strike
counter on it. The same is true for flying, deathtouch, double strike, haste, hexproof, indestructible, lifelink, menace, reach, skulk,
trample, and vigilance.
