Twinferno - Dominaria United (Uncommon) [DMU-149]

Twinferno is a red instant from Dominaria United that offers two versatile options: you can either copy your next instant or sorcery spell, choosing new targets, or give a creature you control double strike until end of turn. This card is valuable in both spell-heavy decks that can exploit the copy effect and aggressive strategies that benefit from dealing extra damage quickly. However, it requires careful timing to maximise its potential.
