Silvers are fun and oh so gross. I'd recommend getting rid of all the tri lands are they are generally slow lands. A better option would be the check lands like Glacial Fortress, Sunpetal Grove, Drowned Catacomb, Dragonskull Summit, Rootbound Crag, Isolated Chapel' Clifftop Retreat, Sulfur Falls, Hinterland Harbor, and Woodland Cemetery.

Could even go an alternate win route through the 10 gates and Maze's End.

Since you are running 5 colour I feel you don't have enough mana ramp within your deck. You need cards that let you drop a couple mana per turn such as Oracle of Mul Daya, Burgeoning, or Exploration.

Thanks for the input. The 3 color lands are a new idea, I used to just have an extra 1x of each basic land. I think I will try the check lands, just have to decide which color combos I want to go with (since I really want to keep at least 1 of each basic land).

I am honestly debating which enchantment to go with. Burgeoning would be good since I usually play in big multiplayer style matches with friends, especially if I put in something like Rhystic Study which could give me card draws during an opponents turn, but I like Exploration a lot as well. I suppose I could do both, but that seems like overkill. Any thoughts?

IMO when choosing between Burgeoning or Exploration I base my decision on how many people I play with unless my deck relies on getting a lot of lands out (my Damia, Sage of Stone deck for example, that's when I run both). In multiplayer I prefer Burgeoning over Exploration in 1v1 Exploration will be better in the long run.
