In the manga, Leo uses a "Forest"/"Morphtronic" Deck focused on Swarm tactics so he can easily Synchro Summon his and Luna's "Duel Dragons". The Deck also features a large amount of Equip Spell Cards for "Power Tool Mecha Dragon" and the "Fairy Tale" series for "Ancient Fairy Dragon". Despite lacking "Morphtronic" monsters, Leo uses "Morphtronicize" to transform his monsters into them so he can use their support cards.
