Weevil uses an Insect Deck. His strategies rely on cards such as "Insect Barrier" or "Cocoon of Evolution" to block opposing attacks while preparing to Summon his strongest cards, "Great Moth", "Perfectly Ultimate Great Moth", and "Insect Queen". Compared to other Duelists, Weevil uses few Magic and Trap Cards, the ones he does use act to protect his insects or allowing him to swarm the field with them.
