Krenko Mob Boss

This is a mono-red Goblin tribal combo-aggro deck built entirely around Krenko, Mob Boss's tap ability — "{T}: make X tokens where X = Goblins you control." One activation snowballs the board exponentially, and with any Goblin lord to widen the count and any of several untap/sac engines, the deck goes infinite. It wins by exploding the board into a lethal token swarm, converting that swarm into direct damage via Purphoros/Impact Tremors/Goblin Bombardment, or assembling an outright infinite-token loop for a same-turn kill.

EARLY (T1–3): Deploy cheap ramp and Goblin bodies — Sol Ring, Skirk Prospector, Goblin Lackey, Ruby Medallion, Arcane Signet — and start building a Goblin count so Krenko's first tap is meaningful. Land a haste enabler if you can. MID (T4–6): Resolve Krenko, Mob Boss and immediately protect/untap him. Even one tap on a board of 4–5 Goblins doubles you; a lord like Goblin Chieftain, Goblin Warchief, or Goblin King compounds it. This is where you look to assemble the infinite line or set up a lethal alpha swing backed by Impact Tremors/Purphoros, God of the Forge. LATE: Close with an infinite loop, a massive Purphoros/Impact Tremors damage trigger burst, or a haste-enabled overrun with Shared Animosity/Coat of Arms pumping the swarm. Last-Ditch Effort and Goblin War Strike turn a wide board into direct damage when swinging is unsafe.

Ramp 8 — repeatable, bigger mana every future turn: Sol Ring, Arcane Signet, Ruby Medallion, Patriar's Seal, plus the sac-for-mana engines Ashnod's Altar, Phyrexian Altar, Skirk Prospector, and the token-scaling Mana Echoes and Howlsquad Heavy. Note that several of these (the altars, Prospector, Mana Echoes) double as combo pieces, not just acceleration. Burst mana 4 — one-shot spikes for a single explosive turn: Battle Hymn, Brightstone Ritual, Seething Song, Jeska's Will — all of which scale off a wide Goblin board and are meant to power out a Krenko turn or storm off. The curve is low and aggressive: average CMC 2.57 with 13 cards at 0–1 and 17 at 2, tapering hard after four. The engine that keeps gas coming is Krenko himself plus Goblin Ringleader/Muxus, Goblin Grandee/Goblin Matron/Imperial Recruiter for refills and Skullclamp turning dead 1/1s into cards.

Keep 3–4 lands (deck runs a lean 35) with early acceleration and at least a couple of Goblins to build a count. Ideal keeps have Sol Ring or another rock, an early Goblin like Skirk Prospector or Goblin Lackey, and a path toward Krenko or a lord. Hands with Krenko plus a haste enabler (Lightning Greaves, Swiftfoot Boots, Thousand-Year Elixir) or a combo piece (Skirk Prospector + an untapper) are premium. Ship no-lander/one-lander hands, and be wary of hands that are all high-drop payoffs with no early Goblins to generate a count — Krenko taps for zero on an empty board.
