A lot like Volcarona V, which is one of the strongest decks in Expanded. Comparing the two...
Basculegion Pros: 1 Prize.
Basculegion Cons: Stage 1, does 20 less damage, and is more vulnerable to spread damage.
The main attacker being stage 1 means your more afraid of ADP since you can't attack until your second turn, but I suppose one workaround would be to go all in with Archie's Ace in the Hole since you'd be using 4 Battle Compressors, 4 Ultra Balls, and a Computer Search anyway, and after the first cheated out Basculegion you can manually evolve the rest so your supporter for turns afterward can go to Boss/Guzma or Ranger... you can also opt to just run a Volcarona V or 2 in the deck as well for the first attack, and hell you'd be better off using fire energies since the attack cost is free and fire energy means you can abuse Fiery Flint, Giant Hearth, and Heat Factory.
Considering Volcarona V has had very little impact on Standard, I'm not sure how much better this will do... on the bright side no ADP means it being 1 prize is more significant, but on the negative side it's much harder to hit high numbers back to back. You're better off just running Rapid Strike Malamar in standard, as the deck has less bricking, an easier time powering up every turn, and also hits a better weakness for when you can't power up too much or don't want to dump all your resources (which isn't even an option for Basculegion).
