Infinite Goblins! (1072 Damage turn 4) (Modern)

http://tappedout.net/mtg-decks/1-goblin-2-goblins-6-goblins/?cat=type&sort=price

Turn 1: Cavern of Souls + Foundry Street Denizen

Turn 2: Mountain + Warren Instigator Attack for 2

Turn 3: Mountain + Goblin Chieftain Attack for 9 (2 + 4 + 3) Cheat out Krenko, Mob Boss tap for 4 goblins on first trigger, giving Foundry Street Denizen +5/0 so you attack in for 14, on second hit cheat out Krenko, Mob Boss tapping for 8 more goblins totaling 16 goblins

Turn 4: Shared Animosity Tap Krenko, Mob Boss for 16 goblins, making your total at 32, leaving 31 untapped. attack with your 29 2/2s for 29x32 = 928. Foundry Street Denizen does 48 = 976. Warren Instigator does 64 = 1040. First strike lets you get your Goblin Chieftain out making 32 more damage come into effect totaling 1072! CRAZY!

Turn 3 win example:

Turn 1: Goblin Guide + Cavern of Souls attack for 2

Turn 2: Mountain + Goblin Guide + Legion Loyalist attack for 5

Turn 3: Attack for 5, leaving them at 8 and use Lightning Bolt + Goblin Grenade

There are lots of different turn 4 and turn 3 combos that will win you the game that you can think of pretty easily yourself :)

Obviously, you don't get a turn three win or even a turn 4 win everytime, that's ludicrous. If they have no removal spells in the first few turns, then you are quite likely to, and with all the lands that come out tapped sometimes you can get too much irreversible damage out there, and then something with haste and a goblin grenade might kill them off. Also, all the lands like City of Brass, Mana Confluence or fetch lands help at killing them. Sometimes it's easy for someone to do 2-4 damage to themselves from lands pretty early on, and that's an incredible boost to your kill pressure. Really fun deck.

Things to make it cheaper would be to exchange the more expensive cards for things like Impact Tremors or some more burn. That's a lot off the price tag. Taking out Goblin Guide and using Foundry Street Denizen is also a viable thing you could do which would take almost another $140 off the price. Trade out the Goblin Rabblemaster for something like Goblin Heelcutter , Hordeling Outburst , or you can be creative. Lots of ways to turn this idea into a budget friendly deck :)
