Undying Aggro Hybrid
The deck is based in getting +1/+1 counters by killing your own creatures and the opponents creatures as well. Then manipulate theese counters with Bioshift or give all of them Trample with Tuskguard Captain.
Use Young Wolf and Strangleroot Geist to attack and buff Rot Shambler.
Ambush Viper and Prey Upon are just the best removals for this deck.
Rot Shambler, Lumberknot and Tuskguard Captain are all counter stackers.
Increasing Savagery, just in case.
Viridian Emissary is the mana fetch of the deck. This guy helps you drop the Vorapede or the Lumberknot earlier in the game. Especially Lumberknot, you want to drop him as soon as possible so as the game goes on he gets bigger and bigger.
If you have an early advantage over your opponent, like when you have a 3/3 Rot Lamber and a Strangleroot Geist, and let's say two other creatures, you can play Overrun and finish the game.
Or if you get to the late game, chances are you have a giant Lumberknot just play the Tuskguard Captain and give him trample, or maybe use it as a counter stacker and attack with a bunch of creatures if one of them is not blocked use Bioshift to make it a monster.
This is a working on deck, accepting sugestions for getting it better.
