Borborygmos Enraged
The earlier Borborygmos was a vanilla beater dressed up as a legend: big, expensive, and inert beyond its swing. This version turns the same creature into a self-fueling artillery piece by closing a loop between two of Gruul's favorite resources, lands and combat damage. The connect trigger fills your hand with lands while dumping the rest into the graveyard, and the activated ability spends those lands as ammunition, three damage a card at no mana cost and no tap. The result is a build-around whose engine accelerates the longer it runs: every hit refuels the gun, and the gun finishes whatever the trample does not. What pays for the otherwise absurd rate of free repeatable burn is the cost structure itself. The damage ability eats a card from hand each time, so the supply is finite unless you keep connecting, and connecting through a board means surviving with an eight-mana 7/6 that dies to most premium removal. The discard cost also rewards a deck stuffed with lands you can afford to lose, which is exactly the kind of land-matters, ramp-heavy shell Gruul wants to build anyway. The design bends deckbuilding toward flooding on purpose, then converts the flood into a finisher. Its cleverness is that the two halves feed each other without any outside enabler: the body draws the lands, the hand spends them, and the cycle only stops when the board does.
