I told you to read smut, not build a commander deck! Kids these days...

I couldn't help it!! D: it just wasn't as sultry as Nissa....

To each their own.

NecroPony I am going to take that out of context and quote that everywhere. Just to let you know. :P

That's fine. It's better thus way

SaniTheCat, I think you need some cheaper land ramping spells to give you a better chance of hitting seven lands faster to flip Nissa. This deck is playing a very high Avg. CMC, having some spells that can get lands faster into play would really help to play your big creatures. Your deck doesn't appear to be budget so my suggestions will not be budget options.

I will first list all my suggestions and then explain my reasoning. Some cards to consider are:

Exploration, Burgeoning, Gaea's Touch, Explore, Summer Bloom, Nature's Lore, Three Visits, Rampant Growth, Primal Growth, Clear the Land, Yavimaya Elder, Sylvan Ranger, Skyshroud Ranger, Sakura-Tribe Scout, Thawing Glaciers

1. Exploration, Burgeoning, Gaea's Touch all these enchantments are green and cheap, letting you play more lands a turn in the early game is what you want to be doing.
2. Explore, Summer Bloom cheap sorceries that let you play more lands a turn.
3. Nature's Lore, Three Visits, Rampant Growth, Primal Growth cheap good land ramping.
4. Clear the Land for three mana you can potentially put up to five lands into play.
5. Skyshroud Ranger, Sakura-Tribe Scout one mana creatures that can put lands from your hand onto the battlefield.
6. Yavimaya Elder, Sylvan Ranger cheap creatures that can get lands into your hand.
7. Thawing Glaciers can guarantee you get a Forest onto the battlefield each turn.
8. Another creature that could be quite good with your overall strategy is Baru, Fist of Krosa. He can give all your creatures a recurring source of trample as well as pump them.

Good luck with your deck.
