Rakdos Combo Goblins (Modern)

To play this deck you need to play it like a real goblin: Sacrifice everything you need to win the game. You dont need to have a board if the oponnent is dead right?

Unlike other mono red goblins, that use a lot of tokens and burn to win the game fast, this version plays almost like a midrange-combo deck. You can do damage to oponnent face with your goblins on board, but you can really finish the game with your goblins abilities to make huge combos. You can have Skirk Prospector + Putrid Goblin + Grumgully, the Generous or Metallic Mimic to make infinite amount of red mana, or having Sling-Gang Lieutenant + Murderous Redcap + Grumgully, the Generous or Metallic Mimic (or both!) to deal infinite damage on oponnent face. The sacrifice cards (Skirk Prospector and Sling-Gang Lieutenant) can have infinite effect if you have a goblin with Persist effect (Pudrid Goblin or Murderous Redcap) and a goblin that get other goblins +1/+1 counters (Grumgully, the Generous and Metallic Mimic), since the persist effect bring the goblin back to the board with -1/-1, but with the +1/+1 buff the -1/-1 counter is neutralized, allowing the goblin to be sacrificed and revived multiple times. Munitions Expert is another resource you have to deal damage on oponnent's creatures and helping maintain the board pressure.

Since you have a lot of 2-4 mana cost goblins, you want to always keep Aether Vial on opening hand, since you dant have a great drop 1 and want them to make sacrifice combos. With Aether Vial on board early you can stack it to drop more than one of your cost 4 goblins for combo, like Sling-Gang Lieutenant and Murderous Redcap. You can just vomit your goblins from hand with no problem since you have great goblins draws like Goblin Matron and Goblin Ringleader. Goblin Matron is great because you can search of one of the goblins you need to combo if you dont have it on your hand. Goblin Ringleader is less consistent cuz it is 8/80. He can either fill your hand with goblins or find none, leaving you with a cost 4 2/2 goblin on board and no new goblin on hand.

I think this list is a lot of fun and thematic. You have a lot of fun combos to do with your creatures effect. Its fun and its GOBLINS! Hope you have fun with that as well.
