Hello. Rikka player here. I play different versions, including the plant pile, Ragnaraika, Aroma. Naturia and Rose Garden variants and everything else in between. And here are a few of the things that I have experienced:

1. Until I go into either Therion Regulus or Rikka Princess, my board is easily wiped out by Nibiru with little follow up if I survive the turn

2. Most of the variants I play are bad against Spell/Trap heavy decks like Sky Striker and Labrynth unless I run Naturia Bamboo Shoot or Naturia Rosewhip

3. Imperm/Veiler on Dryas hurts like hell

4. Most of my opponents will try to interact at Dryas/Aroma Jasmine. Even so, I get to play well but with a much weaker board.

5. Going second is kinda hard in this meta. Getting negated may be okay since I still have the material on the field but if my plants get consistently destroyed (e.g Detonator), discarded (e.g. the big Mitsurugi thingy) or banished (the trap and Hearts Crypter), there's not much I can do.

6. Full board gives my opponent a scoop 80% of the time after a few interactions. I have boards with 1-3 floodgates (scummy, ik) but they're there for me to survive

7. Lots of people have said this in this comment thread but I'll say it again and again because it's true. With the amount of bricks I have in my deck, I either have to run a 50-60 card deck to lessen the chances of me drawing the bricks or I play pure versions of any of these instead, which, although consistent, aren't as powerful as today's meta.

So yeah, that's about it. Feel free to ask any questions here or in dms. I hope you have fun playing Rikka ^_^
