Just paying 4 mana to copy the strongest token around (populate, if you will) is very good, and lots of cards and commanders can give you a token every turn, meaning that this class will draw you a bunch of cards even on your opponents turns
Another major weakness for this deck are card destroying cards like Heavy Storm (recently made limited again), Mystical Space Typhoon (Unlimited), Scrap Dragon, etc
Along with the Commander deck and Turtle Team-Up, the set includes a bundle, draft night box, play boosters, and collector boosters
Yes, Fusion Strike cards can be played with cards from other Pokmon TCG sets, as the Expanded format allows players to build decks with cards from different sets
I made this thread is to show others that I knew my specific submission was off from the standards I was use to for centering, after grading with psa and beckett over a decade
