Soul of Cinder

Indestructible, First Strike, Trample.
At the beginning of your end step, if your Devotion to {u}, {b} or {r} increased this turn, put a +1/+1
counter on each kindled and unkindled creature you control.
{2}{p/u}{p/b}{p/r}:Soul of Cinder gains hexproof and deathtouch until end of turn.
It exists as the Flame's last defense inside its Kiln, protecting it from anyone attempting to link it again,
acting as the ultimate test of their strength.
