Eternatus Vmax Toolbox Combo

Eternatus VMAX is a Pokémon with a unique Ability: if you only have Dark-type Pokémon in play, you have eight spots on your Bench, but you can only play Dark-type Pokémon. This means the deck has to commit to a mono-type build, for a payoff that other decks can simply achieve with the Sky Field stadium. Eternatus VMAX's stats, while respectable, are also nothing gamebreaking, so the deck is pretty weak by the standards of Expanded.

However, I've chosen to include Eternatus on this website because there's one way to build the deck that is absolutely unique and, in my opinion, deserves to be seen.
