Smaug's Fury

Prowess can exploit the spell and +3 damage, but two mana for a temporary pump without protection or card advantage is a weak constructed rate.

Could be wrong if A highly creature-centric prowess shell could value first strike blowouts more than current spell-heavy lists suggest.

Izzet Aggro could test it as burst damage, but Pioneer rewards cheaper spells and removal; this neither clears blockers nor protects its creature.

Could be wrong if An aggressive creature shell with unusually high payoff for combat damage could make it a niche inclusion.

Even the plausible prowess home has far more efficient spells; a two-mana temporary pump is unlikely to beat cheap damage, selection, or interaction.

Could be wrong if A new creature that converts one large pump into immediate lethal could create a narrow combo role.

Legacy's cheap interaction and extreme efficiency leave little room for a two-mana creature-only combat trick with no protection or card economy.

Could be wrong if An unanticipated red creature-combo shell could use the power boost as a lethal enabler.

It can produce occasional favorable combat, but Pauper red decks generally prefer direct damage and cheaper spells over a conditional two-mana trick.

Could be wrong if A creature-heavy red build with key evasive threats could make first strike and reach more valuable.

Red Voltron can use the surprise power and first strike, but a one-shot +3/+0 is highly replaceable and weak against multiplayer removal.

Could be wrong if A commander specifically rewarding combat-damage bursts could make this a more efficient niche finisher.

A +3 power trick that grants first strike wins many creature combats, while reach can punish flyers; it should usually make aggressive red decks.

Could be wrong if Unknown speed, removal, and archetypes may make holding up two mana too costly or reduce combat relevance.
