Krenko, Mob Boss · Pioggia di Impact Tremors

Game plan. A mono-red Goblin deck led by Krenko, Mob Boss: its {T} ability creates as many Goblins as you already control, so the token count grows exponentially each turn. The goal is to turn every creature entering the battlefield into direct damage.

Early game. Sol Ring, Arcane Signet and cheap Goblins: Mogg War Marshal, Goblin Instigator, Beetleback Chief, Goblin Matron and Goblin Ringleader. Goblin Warchief makes Goblin spells cheaper and gives Goblins haste. Swiftfoot Boots, Goblin Chieftain and Howlsquad Heavy let Krenko, Mob Boss tap right away. Goblin Recruiter and Goblin Matron find the key pieces.

The damage engine. Impact Tremors, Purphoros, God of the Forge, Witty Roastmaster and Molten Gatekeeper deal damage to opponents whenever a creature enters. Warstorm Surge makes each creature that enters deal damage equal to its power to any target. With Krenko, Mob Boss and the anthems (Goblin King, Goblin Chieftain, Rundvelt Hordemaster), a single tap can be enough to end the game.

Key cards.

Win condition. With ten or more Goblins and an enchantment that damages on entry, each wave of tokens takes dozens of life from every opponent. Alternatively, finish with Goblin Bombardment, Goblin Grenade and Goblin War Strike. Avatar of Slaughter gives every creature double strike, but use it carefully.
