This is the Rikka Sunavalon deck that I use the most. I mainly use it to take advantage of my favorite monster in Yu-gi-oh: Tytannial, Princess of Camellias. It has excellent synergy with the deck and is really easy to summon with cards like Lonefire Blossom and Snowdrop the Rikka Fairy, and is searchable with Rikka Glamour. Often times when I open with Unexpected Dai I find myself not using my normal summon, so I use it on Lonefire to get Tytannial out. Of course in the side there is also a Naturia Rosewhip/Bamboo Shoot package and Cactus Bouncer. While less reliable, it is really funny to get these monsters out when my opponent does not see it coming.
There are some things here that are a little less traditional but are more fun for me to play. Tytannial obviously and more ways to get to it, but also Orea the Sylvan High Arbiter. While a fairly slow monster, at the right time it is a great monster for stacking the top of the deck, getting some plants in the graveyard, and clearing the opponent's field for game, and the monster is easily summonable with Strenna like Teardrop and Sacred Tree Beast are. You could swap that out and put a third Strenna in there instead if you prefer. Sylvan Dancepione could probably be swapped out for a third Sunavalon Dryas, but I love the link-2 Dancepione play to go for a Hail Mary and hope you get some useful plants off the top. It is beautiful when it works and often times get you back in the game. I play Rikka Tranquility as well as Rikka Sheet, and it's because I find uses out of both traps and I often use Tranq more than Sheet to keep myself alive. Rikka Flurries is that one card that can take care of almost any tower monster. Even if the monster is unaffected by card effects (Like Crooked Cook or Arrival Cyberse @Ignister), if the monster is the only one the opponent has on the field and you have Flurries and tribute a Rikka, they have to tribute their only monster (The effect is something that affects the player, not the monster, similar to how Evenly Matched works).
The side deck are just cards I prefer to play with the current format, Imperial Iron wall for decks that play out of the banish pile like Floo or Swordsoul, Twin Twisters for back row decks, and Ghost Sister and Spooky Dogwood because it's funny. Change around those cards to your preferences.
I mostly made this to share my creation with the community. Enjoy!
