Uncontrollable Anger

In Commander, Uncontrollable Anger finds its best home on commanders or key creatures that want to attack every turn — the bounce-on-death clause turns a single copy into a persistent threat multiplier rather than a one-shot buff. Pauper is where it sees the most legitimate play, since the card pool is shallow enough that a reusable haste-and-pump Aura at common has real value, particularly in aggressive red decks that expect their creatures to trade. Legacy, Vintage, and Modern are all legal but offer no competitive reason to run it — the effect is too slow and too narrow against the threats those formats produce. Oathbreaker mirrors the Commander read: fine if your planeswalker or signature spell creates a loop that benefits from the recursion, irrelevant otherwise.
