need to put the finishing touches on my plant deck?

Your deck looks good at the moment, and you explained to me a few things I needed to know about this deck.

- For Spells, I think you should take out 1 Book of Moon and add in a Brain Control. MST and Lightning Vortex also work well but there isn't any space for them.

- Traps are perfect, no need to change.

- For Monsters, take out 1 Mystic Tomato and side 1 Caius. Add in 2 Botanical Lions OR 1 Botanical Lion and 1 Sangan.

I don't know much about Plant decks, so if I did anything wrong then please tell me.

The best I can think of right now is adding some Tuner monsters and Black Rose Dragon, as your main Synchro. Try to add the "Black Garden" field spell. It'll get you precious Plant-type tokens. Also, you should have 2 Wall of Thorns instead of one. And, last but not least, you should try to add the Phoenixian seed ... Hope it helps
