The inner card holder is made to fit the flat lid piece and is simply is put in place by friction, I used double sided tape to make it more secure
This is going to be the biggest fusion of all time
Your goal is to assemble the following pieces: Team Magma's Secret Base, Weavile, Reuniclus, Klefki, two beefy Pokemon to hold many damage counters (Magikarp & Wailord-GX, legal at Dallas Regionals, is ideal thanks to its huge 300 HP), and of course Unown DAMAGE in the Active
I still like the Spell line-up, its pretty solid and I dont think I would change it unless all of the sudden every meta deck used their extra deck, in which case I would switch back to 3 Shaddoll Fusion, as it stands though I dont like that cards except for against Burning Abyss, and theyre even learning ways to play around that, so its not even spectacular in that match-up, at least as much as El Shaddoll Fusion is in most instances
