Tome Fire

Tome Fire can be your commander.
When Tome Fire enters thr command zone, put a focus counter on it. The next time you pay for Tome Fire, it is not cast. Remove all focus counters from it.
As long as Tome Fire has no focus counters, it has Flash and you may pay {b}{b}{r} instead of its cost.
Search your library for a instant or sorcery. Reveal it, and put it into your hand. All players lose life equal to its casting cost.
