Protection from red

Beasts of Bogardan gets +1/+1 as long as an opponent controls a nontoken white permanent.

When Bogardan Firefiend dies, it deals 2 damage to target creature.

Bloodthirst 1 (If an opponent was dealt damage this turn, this creature enters the battlefield with a +1/+1 counter on it.)

Flanking (Whenever a creature without flanking blocks this creature, the blocking creature gets -1/-1 until end of turn.)

Flash (You may cast this spell any time you could cast an instant.)

When Bogardan Rager enters the battlefield, target creature gets +4/+0 until end of turn.

Cumulative upkeep (At the beginning of your upkeep, put an age counter on this permanent, then sacrifice it unless you pay its upkeep cost for each age counter on it.)

When a player doesn't pay Heart of Bogardan's cumulative upkeep, Heart of Bogardan deals X damage to target player or planeswalker and each creature that player or that planeswalker's controller controls, where X is twice the number of age counters on Heart of Bogardan minus 2.
