Blastoise Solo Event

Trying to figure out what exactly I need for the Blastoise Event. I haven’t done a lot of the Pikachu Deck due to Mewtwo being meta, The Venasaur Event, & now Celebi being Meta. If I need to, I will pull the Pikachu Deck for the time being. I’m still missing 3 from Mythical Island.

Here’s a list of all I have: Magnemite (2), Voltorb (1), Electabuzz (GA)(1), Zapdos EX (1), Blitzle & Zebraska (2 of each), Tynamo & Eelektrik (2 of each), Helioptile & Heliolisk (2 of each), Pincurchin (2), Pikachu EX (1), Pikachu (MI) & Raichu (MI) (2 of each), Joltik & Galvantula (2 of each), Dedenne (2), Pikachu (Promo)(2), Magnemite (Promo)(2), Giovanni (1), Sabrina (2), Pokémon Flute (2), Blue (2), & Leaf (2). Poké Balls, Oak, Potions, & X-Speeds are already in by default.

Thanks in advance.
