Spam Naganadel then your opponent knocks out Exeggcutes until they have one prize card remaining, then repeat this process until you're ready to use Bellsprout's "Venoshock" attack to do tons of damage. Play this deck with the deck "Absol, Pidgeot and a bunch of energy" to get a huge attack.
Naganadel can reuse its GX attack thanks to Vaporeon with Misty & Lorelei, because Naganadel is a [W] type when Vaporeon is in play.
