Amok Time

Creature-heavy decks can turn the first chapter into removal and later reclaim a threat, but three mana and the delayed payoff are costly for an aggro deck.

Could be wrong if A slower, creature-based Standard could make the fight-plus-regrowth package a recurring midrange card rather than fringe.

The Rock can value a conditional fight spell that eventually returns a creature, but Pioneer removal and threats make this three-mana delayed exchange inefficient.

Could be wrong if An attrition-heavy Pioneer metagame or a dense creature-recursion shell could make its delayed card return more valuable.

A three-mana, creature-dependent fight effect is well below Modern's interaction rate, while returning a card to hand two turns later is rarely enough tempo.

Could be wrong if A proven green creature-combo or sacrifice shell that specifically rewards both fighting and recurring creatures could create a niche.

Legacy's mana efficiency and interaction make a three-mana Saga with conditional removal and a delayed return-to-hand effect an unattractive exchange.

Could be wrong if A future low-cost creature engine that exploits Saga chapters or repeated creature recursion could give it a narrow home.

Creature-recursion or Saga decks can accept the delayed value, but one conditional fight and 3 life are modest effects in optimized multiplayer.

Could be wrong if Dedicated Saga recursion or commanders that reward creatures dying could turn its three chapters into a stronger repeatable package.

Immediate fight can remove a creature, then the Saga gains life and recovers a fallen creature; that is strong incremental advantage when you have a board.

Could be wrong if Unknown format speed, creature sizing, and removal may leave the fight chapter unreliable or make the delayed third chapter too slow.
