Affinity for artifacts (This spell costs less to cast for each artifact you control.)
When Krang enters, if you have fewer than four cards in hand, draw cards equal to the difference.
Krang gets +1/+0 for each other artifact you control.
Flood the board with cheap artifacts to cast Krang for next to nothing, refill your hand to four on entry, then swing for huge damage since Krang grows with every artifact you control. You play a mono-blue artifact midrange/aggro deck that rebuilds quickly thanks to the ETB draw, recasting Krang repeatedly after removal.
Affinity makes an 8-drop routinely cost 1-3 mana, so Krang hits the table early
Built-in card advantage every cast keeps your hand stocked, blunting removal
Scales into a one- or two-shot kill threat in token/treasure-heavy artifact builds
Mono-blue gives access to the best counterspells, card draw, and protection
A single creature wins; if Krang is exiled or kept off the board you stall
Mono-blue lacks efficient removal and direct interaction with the board
Casts artifacts off the top of your library, refueling the affinity engine and digging for threats.
Lean into evasion and protection—add Whispersilk Cloak, Lightning Greaves, and Rogue's Passage so Krang reliably connects, plus counterspells like Swan Song and Fierce Guardianship to shield it. Increase cheap artifact density (Mishra's Bauble, Ornithopter, Sol Ring, mana rocks) to slash Krang's cost and boost power, and add recursion or reanimation-proofing so you can recast cheaply after removal. Top-end upgrades like Urza, Mystic Forge, and a fast mana base turn the deck into an explosive turn 3-4 threat.
