Magical Leaf (from Venap line) could be added onto Tropius's Egg Moves, as it's a level-up move in RSE.
Also, I've edited and added a few things to Tropius's level-up moves:
-- Leer
-- Gust
7 - Growth
11 - Razor Leaf
17 - Stomp
21 - Whirlwind
27 - Ancientpower
31 - Body Slam
37 - Leaf Blade/Air Cutter*
41 - Synthesis
47 - Magic Dust
51 - Sunny Day
57 - Tempest
61 - Grasswhistle
67 - Floral Storm
Not sure about Leaf Blade, as it's Sceptile's signature move. Still, it fits Tropius. Air Cutter is an alternative in that slot. I can't see Tropius camouflaging anywhere but the forest, and even then it's a stretch. Sky Attack also doesn't fit very well, seeing as Tropius's appearance makes it seem like it can't go very fast.
