Krenko, Mob Boss + Skirk Prospector + Tannuk, Steadfast Second

Krenko, Mob Boss

Skirk Prospector

Tannuk, Steadfast Second

How it works

1. Activate Krenko by tapping it, creating a number of 1/1 Goblin creature tokens equal to the number of Goblins you control.
2. Activate Skirk Prospector by sacrificing Krenko, adding .
3. Choose to return Krenko to the command zone from your graveyard.
4. Activate Skirk Prospector by sacrificing a Goblin, adding .
5. Repeat step 4 until you have enough mana to cast Krenko.
6. Cast Krenko from the command zone by paying 2 plus commander tax.
7. Repeat.

This loop uses Krenko, Mob Boss to flood the board with Goblin tokens, which instantly gain haste thanks to Tannuk, Steadfast Second allowing them to act immediately or be fed into the machine. Skirk Prospector acts as the engine, turning those newly minted tokens (and eventually Krenko himself) into the red mana needed to keep the cycle going. Whenever Krenko is sacrificed to Skirk Prospector, sending him back to the command zone allows you to continually replay him using the accumulated mana from the sacrificed Goblins, exponentially increasing your token output with each iteration.
