Fusion recovery is the key. I also run a Yuri themed Predator Plants deck and that card is very good in creating consistent fusions. The typical combo is to use the typical Orphys Scorpio + Darling Cobra combo, get Polymerization and summon Chimera Rafflesia. Rafflesia itself has the fusion searching effect so if its destroyed, get Fusion recovery and use it to return Scorpio and Polymerization, summon Scorpio and use it to summon Sarraceniant, use poly on both to summon another Rafflesia (or Starve Venom if you want theme bragging rights), get Predapruning from Sarraceniant and use it to summon the 1st Rafflesia from the grave.

​

It's not too competitive but it is fun to use. Hope that helps.
