Notes & Combos
Plant power! The sunavalon engine turns this deck into a more combo oriented deck which is pretty fun to play. It baits out interruption and even if you don't resolve the sunavalon engine, the rikka stuff is already good enough win you games. Past turn 1/2, it gets really hard for other decks to outgrind the rikka engine. I'd say this is a pretty standard list, and is a good starting point for anyone trying out the deck.
I like hard opening the field spell, so I run 3 konkon + terraforming, but you could cut the terraforming and even just play 2 konkon. Some people also like playing primula at 2 for the glamour interaction (in case you hard draw primula), but I would rather cut the second one for a tech card. When dancepione comes out, you can cut the second healer for her.
Only problem with rikka from my playtesting so far is that it sucks against backrow heavy decks, so slotting in backrow hate definitely helps out depending on the meta.
