So this is a try to make a ramp deck using walls instead of elves. It may start very slowly compared to other modern decks with Garuks and untapping forests, but you can end up with a monstrous Colossus of Akros by turn 5, which means you'll have a 20/20 with trample next to some walls. That could be fun.
I got some cards out of the Maybe board into the Sideboard just because I figured this deck worst nightmare would be a blue control kind of thing. So to keep strong creatures on the board, there's that.
It actually has happened to me while I was testing the deck here. Here's how it went:
Turn 1: Forest
Turn 2: Rogue's Passage and Overgrown Battlement
Turn 3: Rogue's Passage and Traproot Kami. Tap Overgrown Battlement to generate 2 mana and play another copy of it.
Turn 4: Forest and now you have 10 mana. I used 8 to summon the killer defender Colossus of Akros. With the spare 2, you could play a Canopy Cover to make sure it stays on the board, but I didn't have any on me =. Having this new defender on the board will let you generate 2 more mana on your next turn (from each of yours Overgrown Battlement.
Turn 5: If you decide to make Colossus of Akros monstrous (as I did), you'll still have some leftover mana, which maybe be used to get some good stuff. You could play another defender as Axebane Guardian and Traproot Kami or, if a miracle happens, Revenge of the Hunted to make your Colossus a 26/26 indestructible monster that can trample and cause damage to everything on the other side of the board. If it got a Canopy Cover earlier, it's a one-hit-kill if the enemy doesn't have anything flying. In my test, I got to use Rogue's Passage on the 6th turn and swing for 20.
However, if you had a Heroes'Bane instead and got it on the battlefield on turn 4, you could have doubled its power once then and twice on the 5th turn. That'd make it a 32/32. Pretty green, right?
If it was a Hydra Broodmaster, you would be able to make at least 7 7/7 new hydras, and turn the first into a 14/14.
If no big monster show up on your hand, you could use Genesis Hydra or Nissa's Revelation to let you find more creatures, be it defenders (with the hydra - though if you have enough mana, it could mean you get to play two big creatures on the same turn) or anything (using Revelation).
Skarrg Goliath is our surprise magic. If you just have one card in your hand as you swing with, say, that 14/14 Hydra from before, the enemy could block it with a weak 1/1 token or whatever, but if you use Bloodrush, the Hydra becomes a 23/23 with trample and could get you a win. Aside from that, it's a good heavy hitter with trample.
Outland Colossus works nicely with Canopy Cover and Rogue's Passage, making it a 12/12 even if you don't have enough mana on the field to summon the bigger guys.
To make it short: use your defenders to hold out as you bring the big guns into battle.
