Use "Debris Dragon" and then use "Inferno Reckless Summon" to get 2 more "Gephyros". Synchro for "Lavalval Dragon", then ram the other 2 "Gephyros" into one of your opponent's monsters. Use each one to Special Summon "Evolsaur Vulcano", who can then Special Summon any Evolsaur monster from your Graveyard. This will leave you with 4 Level 4Dinosaurs. End your Battle Phase and Xyz Summon 2 "Evolzar Laggias".
