Burst of Energy card art
Burst of Energy untaps any permanent for one mana at instant speed — a rate that enables tap-ability loops, combat tricks, and mana doubling on demand. Under Isochron Scepter, it becomes a repeatable engine piece that costs only two mana per activation, which is where the card stops being a niche trick and starts being a combo linchpin.

Commander is where Burst of Energy does its best work, slotting into any deck that wants to untap a creature with a powerful tap ability — Krenko, Mob Boss, Selvala, Heart of the Wilds, or any artifact-based engine. Pauper gives it a second legitimate home, where cheap instants with real mechanical upside are scarce and the card earns its slot on rate alone. Legacy and Vintage are legal but uninterested — Burst of Energy doesn't clear the bar in formats with access to free spells and more broken untap effects. Oathbreaker mirrors the Commander case: if your planeswalker or signature spell rewards repeated activations, this is a live inclusion.

Price Context

Current price

$0.21 bulk tier

At $0.21, Burst of Energy is firmly bulk — you're picking it up for pennies in a trade binder or a budget order. Bulk commons with genuine combo applications tend to tick up slightly once a deck goes viral, but at this price it's a no-risk include for any deck that wants it.
