1. Weakness policy Rotom-Mow is unadvisable, it doesn't carry priority or high enough speed to make good use of it once it's got the boost. Addtionally, Will-o-wisp + Hex isn't a bad combination, but it gives them two turns to hit you, and that's not great if they're faster than you or they're a special attacker. Light Screen also is dodgy on a more offensively based pokemon.
2. Mega Venusaur is a decent pokemon, but you're running a very bad set. I see little point slapping full speed on a pokemon with base 80 speed (After it mega evolves) and it doesn't have Chlorophyll after that anyway. Mixsaur is okay I suppose, but without any EV investment, GL with that.
3.Sunflora is crap really, and if you're even considering using it Solar Power is a must to give it some firepower. Running Chlorophyll? Go use Exceggutor or something. Anyway, this guy is basically nonexistant even in NU >.>
4. Maractus. Outclassed. Maractus is outclassed as a Grass-type in nearly every aspect. Roselia and Cacturne outclass it as a Spikes user, while Victreebel, Exeggutor, and most other Chlorophyll Pokemon outclass it as a sun sweeper. - Gen 5 Smogon description,
5. Trevanent, try putting will-o-wisp somewhere, but it looks okay
6. Gogoat - Attract. Really?. I'm getting lazy so bla
You said to me how this team functioned as a mono and a smogon doubles team. I watched Pika 3-0 you in doubles, and monotype in doubles is reaaallly dodgy.
If you've actually tested the team out, you should probably know the gaping flaws
