Golgari Hydras! It is essentially a mana ramp deck focused on destroying your enemies with hydras the size of Congress's disapproval rating.
The Rampers:Elvish Mystic is a good one drop that gives you a quick green mana when it's needed. Sylvan Caryatid is an essential mana ramp card that doubles as a blocker, and isn't affected by removal. Voyaging Satyr is in there primarily to untap Nykthos, Shrine to Nyx and tap it again, giving you almost double the mana.
Liliana of the Dark Realms
is in there for mana purposes, potentially giving you four mana per Swamp.
The Colossi: Kalonian Hydra is a doubling factor in order to ensure damage to your opponent. Hard to deal with. Doubles the powers of all other hydras you have out each turn Mistcutter Hydra absolutely destroys control. Polukranos, World Eater starts out small, but can grow and become a field wiper. Vastwood Hydra can serve as a contingency plan for pumping up another creature when it dies. EXTRA COLOSSUS: Lord of the Void, a typically hard to pay the mana for card, has absolutely destroyed everything in this deck. It serves as an excellent contingency plan.
Corpsejack Menace......look at your hydras, then look at it's effect. You're welcome. Especially deadly with a Kalonian on the field.
Contingency Plans: Lotleth Troll and Scavenging Ooze make good "just in case" cards.
Removal: Abrupt Decay and Putrefy. What more do you need?
Need a Hydra now? Grisly Salvage is your friend.
Need to ensure a kill? Bow of Nylea is your friend.
Maximum killshot: 913 damage (both Kalonians, a Mistcutter, a World Eater, and two Corpsejacks on the field)
Have fun mercilessly crushing your enemies.
