Roar of the Kha gives your whole team +1/+1 and first strike until end of turn for two mana — or for free when imprinted on Elite Arcanist. Outside that specific shell it's a narrow combat trick, but inside it, the free-activation ceiling is high enough that the card earns its slot.

Roar of the Kha is legal in Commander, Legacy, Modern, Vintage, and Oathbreaker, but it's effectively a Commander card — the formats where you can build around Elite Arcanist and zero-cost activations are the ones where it does anything interesting. In Legacy and Vintage the card is too slow and too conditional to see play when instant-speed options are cheaper and more impactful. Commander is where Roar of the Kha belongs: token strategies and go-wide aggro decks can turn the first-strike anthem into a blowout, especially when the activation cost drops to zero.
