Exponential Growth (PRM-90136) is a green sorcery from the Magic Online Promos series. It doubles a target creature’s power a chosen number of times until end of turn, applying each doubling sequentially. That sequential doubling can generate very large single-turn power spikes and pairs strongly with temporary buffs or damage-on-attack effects.
