For a full overview of the deck's strategy, do see my ABCDragoon 2.0 (ft. Skill Drain) build.

This variation of the deck cuts out Skill Drain and Dragoon in order to instead utilize Destiny HERO - Destroyer Phoenix Enforcer and Artifact Scythe which can respectively be brought out through Predaplant Verte Anaconda and Artifact Dagda. The extra and side decks are still up to debate, though, as is whether this build is better than the Dragoon variant.
