Goblins of Korvold Keep (EDH / Commander)

Goblins will always have a special place in my heart: my first ever commander deck was a Krenko, Mob Boss deck, and winning with a ridiculous army of goblins was - frankly - the most fun I've had in the game. I also love Korvold. I had a lot of fun with my former Korvold build. But I was looking for something new, I was missing my old goblin friends, and I ended up with goblin-tribal Jund and I'm not sorry about it.

Combos

1. Food Chain + Squee, the Immortal = Infinite colored mana (NOTE it can only be used to cast creatures)
2. Grumgully, the Generous/Rhythm of the Wild/Mazirek, Kraul Death Priest/Metallic Mimic + persist creature + Any free sac outlet = Infinite ETB, death, and sacrifice triggers

The persist/ETB counters loop is quite fun. It would work with any of the other creatures that have persist, although of course in this deck I'm sticking to a goblin-tribal theme. Persist creatures in this deck are: Putrid Goblin, Murderous Redcap, Scuzzback Marauders.

Payoffs

Take the above persist loop and do it while anything that triggers on death or sacrifice, and you have an infinite combo with added benefits. You can draw your deck with Korvold on the field (or deck yourself for a spicy go-out-with-a-bang finisher); have infinite mana with Pitiless Plunderer; infinite damage with Mayhem Devil or Pashalik Mons; you get the picture. You can also get some of these benefits with some of the sac outlets, like Ashnod's Altar for infinite colorless, or Goblin Bombardment for infinite damage. Go wild. One combo, many possibilities. :)

The Food Chain/Squee loop will only generate mana for casting creatures, thankfully your commander is a creature! I would wait until you have a normal sacrifice outlet on the board to do this one. Generate as much Food Chain mana as your heart desires, then while that mana is floating, get Korvold out (if he isn’t already), and then begin sacrificing Squee and casting him from your graveyard using the floating mana from Food Chain. Do this loop until you’ve drawn into whatever cards you want, or Korvold is big enough, etc. Many possibilities.
