Devoted Firestormer

While Devoted Firestormer is on the battlefield,
cards can't transform and it can't be day or night.
Whenever a creature card you don't control dies,
this creature fights target creature you don't
control. If you do, after this ability resolves, put a
+1/+1 counter on this creature for each time
you've used this ability in this game, and a first
strike counter on target creature.
