Rather than the normal plant combo, this deck aims to win through control with the field spell, Rikka Princess, and Petal and Tranquility and then bounce back with a lot of extension and a toolbox of different plant xyzs, links, and synchros! This is my personal favorite way to play plants, even if it is by far not the strongest way to play plants.
Main combo consists of using Petal (or a way to Petal) then get Mudan, the field spell, and the two level 4s to end on Strenna, field spell, and Petal and Princess in grave with Tranquility set. Very unassuming but it can easily get out of control for the opponent. After that it uses whatever it has at its disposal to secure victory or win the grind.
Hope you guys enjoy!
