I remember from a few years ago I remember that quad sigilyph (immune to EX attacks) was a deck that received a decent amount of play. Now that hex maniac is rotated, and decks like Gardevoir GX and Zoroark GX/Lycanroc GX control the format I feel like hoopa may have some potential. I created a list, and I am open to ideas. The deck may have problems with stuff like baby zoroark, baby volcanion, gallade, and greninja, but I feel like a high hammer count could help with those. Thank you in advance.
