This is my Budget-Infect-Deck. I just play it for fun, but i'm surprised that it works pretty well.
Most of the games, Blight Mamba does the major part of the work. It can regenerate and with Oran-Rief, the Vastwood , Ordeal of Nylea and Curse of Predation , it's really difficult to get rid of it. While the opponent gets some poison counters thanks to Blight Mamba , the Proliferate-effects are the biggest strength of this deck in combination with +1/+1-Counters, -1/-1-Counters and especially poison counters.
Obelisk Spider heals me every time the opponent blocks my creatures and it can block and cripple flying creatures itself. With some +1/+1-Counters on it, it can be a really strong wall with some nice advantages.
Tangle Angler ensures that my stronger attackers don't get blocked when i want to distribute larger amounts of poison counters and it can cripple one dangerous creature.
Spinebiter deals 3 poison counters at a time and can be very dangerous if i get some +1/+1-Counters on it.
Plaguemaw Beast is really good for Proliferating when i can't attack or need to stack large amounts of counters in a short time. Sadly it hasn't Infect, but it can block some small creatures.
Reaper of Sheoldred is really perfidious for all creatures which can be blocked by it.
Plague Stinger is another cheap creature and is my alternative attacker when i don't have Blight Mamba and is difficult to block as well.
Ordeal of Nylea gets me basic lands directly onto the battlefield and some +1/+1-Counters.
Spread the Sickness is a good destruction and gives me Proliferate. The high costs are affordable thanks to Ordeal of Nylea .
Grim Affliction can easily cripple or destroy small creatures and gives me Proliferate.
Curse of Predation stacks +1/+1-Counters for Ordeal of Nylea when the enchanted creature attacks and gets more counters on my other attackers.
Sixth Sense is in this deck because i like drawing cards. It's a cheap enchantment and can be very useful, but isn't that necessary.
Oran-Rief, the Vastwood is a very good green land that can give me +1/+1-Counters without attacking.
