Hellfire Titan

Incinerate {r} ({r}, {t}: Put a fire counter on target creature. At the beginning of your upkeep, if any creature has three or more fire counters on it, its controller sacrifices it.)
Each creature with a fire counter on it has
"Incinerate {p/r}. ({p/r} can be paid either with {r} or 2 life.)"
Fire knows no friend or foe, only destruction.
