Grow Extra Arms puts a substantial power and toughness boost on a creature while also handing it a third arm's worth of additional combat presence — the effect is immediate and the rate is competitive for what green Auras do at this cost. Miles Morales decks run it because the combination of stat inflation and whatever rider the card provides lines up cleanly with what that commander wants to do in combat.

In Commander, Grow Extra Arms earns its slot in go-wide or Voltron strategies that want cheap Auras stacking bonuses on an already-threatening creature — Miles Morales is the primary home, but any commander that rewards buffing a single attacker considers it. In competitive 1v1 formats like Modern and Pioneer, Auras live or die by their interaction with hexproof and lifelink payoffs, and Grow Extra Arms needs to prove it can keep pace with the rate those formats demand. Pauper is legal, which matters — common Auras with clean stat bonuses see real play there when the effect-per-mana is tight enough.
