I have a regional coming up in a week or so and I just cannot for the life of me think of what deck to play, whether that be for fun or competitively.
I have the following cores(some might be missing a card or two):
Crusadia
Mermails
Salads
Cyber Dragons
Dinosaurs
Pendulums(Endymion/Magicians)
Zombies
BA
Sky Striker
True Draco
SPYRAL
Altergeist
Prank-Kids
Mekk-Knights
Shaddolls
Subterrors
Impcantation Shinobirds
Half cores:
Invoked
Trickstar
ABC
Paleo
On top of this I have literally every staple card at the moment other than phantazmei and the secrets/ultras from the most recent sets that are seeing play.
Go wild, combine cor
