The idea behind this deck is to get out a ton of cheap defenders, give them some damage through Doran, The Siege Tower, and then allow them to attack via Rolling Stone, Warmonger's Chariot or the ability of Wakestone Gargoyle.
Doran is an important card to the deck, but since I'm cheap I decided to only purchase 2 copies of him, and use Treefolk Harbingers to pull him in instead. Recover is also in the deck to pull him back from the graveyard if needed.
Even without Doran, there are a couple alternate win conditions you can use. First, Vent Sentinels get deadly once you have 4+ defenders in play, which is very easy to do since they are all cheap, and tough to remove through direct damage. Alternatively, Strength of the Tajuru or Genesis Wave will let you flood the board and give you some decent damage output.
Overgrown Battlements are amazing in this deck and should give you all the mana you need to cast some huge spells once you're 5 or 6 turns in; and having all defenders gives you plenty of time to stall your opponent until then. If you need to, you can draw some extra life from the Tree's of Redemption to stay alive.
This deck could certainly be improved with some more expensive cards; mainly some Dual Lands to acquire Black and Red mana more easily, and another Doran.
