Notes & Combos
Without the Sunavalon/Sunvine cards, pure Rikka is a control deck. Try to end on some combination of Sheet and Strenna on the field, Princess in the hand or GY, and hand traps. Tribute Strenna to Special Summon Hyperyton or Teardrop for additional interaction.
The other Xyz Monsters never came up. Kanzashi can sometimes facilitate an OTK if you also have Teardrop to trigger her effect, but it's generally easier to just rebuild your interruptions on turn 3 and continue the control win con.
Max copies of Mudan, Konkon, and Glamour to ensure that you see Konkon even if your opponent disrupts you. The second copy of Sheet serves the same purpose, and also allows for better rebuilding if needed. Strenna can add it back from the GY, but it's easier to just grab a second copy with Konkon or Mudan.
