First strike

Whenever you cast an instant or sorcery spell, "Fire Fist" Ace deals 1 damage to target opponent. Add {R}.

{R}: Exile "Fire Fist" Ace, then return it to the battlefield transformed under its owner's control. Activate only as a sorcery and only if you've cast three or more instant and/or sorcery spells this turn.

: (As this Saga enters and after your draw step, add a lore counter.)

I: Fallen Heir deals 3 damage to target opponent and each creature they control.

II: Create three Treasure tokens.

III: Until end of turn, you may cast instant or sorcery spells from any graveyard. If a spell cast this way would be put into a graveyard, exile it instead. Exile Fallen Heir then return it to the battlefield (front face up).
