Notes & Combos
Honestly crazy how much this deck won ending on one interruption or bricking half the time. Elegance is a necessity going second in case your normal summon gets interrupted. Going one for one into Cutia into fancia is an interesting play in case your cutia gets booked or crackdowned since fancia is also a starter.
Go for musica turn 1 if you already have Angelia for Coolia (depending on match up) then go for harmonia turn 2 if you go first. Going second you basically pray for an extender like one for one or elegence or a spell that helps play around their field. Harmonia is great going second if you can get to it. In order to use it's pop effect. You can usually use Cutia(9) Angelia(3) and Coolia(1) to get the pop but you often need Gracia(4) to get the field spell and adding more means less interruption to draw into.
Coolia works well against some popular decks like heroes (stratos or blazeman), PK (breaksword), blue sky, and every starter in red dragon decks. Musica is a good counter to magicians circle and then you just out resource them in the worst case.
Deck isn't optimized and I might test a few changes like Dreamia instead of Beautia for some extension plays. Also Extra deck was barely used unless I was already winning.
