Warp Blast isn't a standard Magic keyword—it appears to be a made-up or misremembered name, so there's no official rules text to explain. If you encountered it in a custom set, a digital game, or a fan card, its behavior would depend entirely on that source's design.
If you're thinking of a real card, you may be blending a few together. "Pyrotechnics" and "Fireblast" are direct-damage burn spells, while effects with "warp" flavor often involve blinking, exiling, or temporarily removing permanents. Double-check the exact card name in Gatherer or Scryfall to get accurate wording.
For Commander specifically, always defer to the printed Oracle text and the current Comprehensive Rules. If you can share the card's actual name or text, I can break down its rulings, common mistakes, and multiplayer applications precisely.
