Abundance + Borborygmos Enraged + Curiosity + Phyresis

Abundance

Borborygmos Enraged

Curiosity

Phyresis

How it works

1. Activate Borborygmos by discarding a land, dealing three infect damage to an opponent.
2. Curiosity triggers, causing you to reveal cards from the top of your library until you reveal a land card, put it into your hand and put all other cards revealed this way on the bottom of your library.
3. Repeat.

This vicious loop turns Borborygmos Enraged into a lethal one-man firing squad by granting him infect with Phyresis and a way to never run out of ammunition. By discarding a land to deal 3 damage, you trigger Curiosity to draw a card, which Abundance replaces with a guaranteed land straight from your library to your hand. As long as you keep feeding lands into Borborygmos Enraged's activated ability, the resulting damage infects your opponents out of the game while constantly refueling your hand for the next iteration.
