Notes & Combos
Diva is a chokepoint but also an incredible addition to the deck. She alone is a lvl 10 Synchro, and thanks to Accel Synchro it's even unaffected and summoned during the opponent's turn. Furthermore, Guitar Gurnards Duonigis lets you banish the top 2+ cards of your opponent's deck so you know what you're facing in advance.
Ideally you wanna open access to Diva + a 4 to special summon, or Paces + a couple of fish in hand. Can manage very well a grind game, even without a 3rd Arionpos. Also don't be afraid of shotgunning Shifter, you can easily go one turn without the graveyard.
