To summon the Cerberusmon:werewolf mode for free, we have to destroy another digimon names “Cerberusmon”. But it is a bit wasting if it is simply destroyed. So we cast Rematch! option card on [BT4-083] Cerberusmon, use this digimon to attack security, then if it dies, it goes back to life, if it can suvive, then we also can destroy this digimon to get 2 draw, then summon the Cerberusmon:werewolf for free. The “werewolf mode” with haste can do another security check at that turn.
