All the Megazoo deck will use the maximum copies of Magnadramon and Puppetmon, it is a must. [Bt2-039] Magnadramon is to recover up-to 2 security when played and [BT2-049] Puppetmon will rest 1 opponent's digimon and all opponent's digimon cannot make active in opponent's next turn, this help to at least delay one more turn of security attacking.
For the option card, if the deck is using LV2 blue digitama Demiveemon and LV3 jamming Veemon, then Wolf Claw (Kaiser Nail) will be use in their deck. Wolf Claw is in the best use to take out LV6 Puppetmon or Volcanicdramon from digivolution source to trigger their "when played" effect. If the Megazoo deck uses LV2 digitama and LV3 digimon in red color, then Gaia Force (Terra Force) will be included. In my opinion, Gaia Force is too expensive to use so red would not be in my preferable choice for Megazoo. Using blue will give more draw power from Demiveemon digitama because its LV3 is jamming digimon, and also can use [ST2-16] (7 costs) to return 1 of opponent's digimon to their deck.
