Notes & Combos
Choose to go second and pop off (normal Faris combo --> Increase --> Vyon --> Poly --> Sunrise --> Miracle Fusion --> Wake Up Your Elemental Hero).
I chose Armed Neos for the Neos Fusion target rather than Rainbow Neos because it kills your opponent's board without needing to shuffle back any resources, and provides a follow-up next turn if you don't win that turn (Special summoning a Neos Wingman; Feel free to try out Cosmo Neos for this play, but extra deck space is tight because of Super Poly targets).
You should be able to out most boards in the event, especially if you open Super Poly (which is why cards like Gaia and Starving Venom are played in the extra deck).
If you go first, try to make an end board with Plasma, or Favorite Contact (Super Poly works too but you have to hard draw it) to make Shining Neos Wingman.
