, Sacrifice an artifact: Put a +1/+1 counter on each Goblin you control.
Whenever an artifact is put into a graveyard from the battlefield, you may pay . If you do, create a 1/1 red Goblin creature token. It gains haste until end of turn.
Flood the board with Goblin tokens by feeding cheap, recurring artifacts into graveyards, then pump the whole team with Krenko's counter ability before swinging for lethal. You ramp early, deploy token producers and artifact fodder, then convert a wide board into a massive haste-fueled alpha strike.
Doubles as both a token engine and a free anthem in one 3-mana body with haste
Treasure and clue tokens trigger free Goblins, turning ramp into an army
Cheap to recast, so it recovers quickly from removal
Goes very wide very fast, threatening huge burst damage
Mono-red lacks card draw and struggles to refuel after a board wipe
Heavily reliant on the commander; without Krenko the deck is just small Goblins
Vulnerable to sweepers, Pyroclasm effects, and graveyard hate on its engine
Both abilities cost mana/sacrifice, making it slower than pure Goblin aggro
