Krang, Master Mind was just printed in the Teenage Mutant Ninja Turtles set (March 6, 2026) and it has made an immediate impact on Modern Affinity. Since release, it appears in exactly 50% of Affinity maindeck lists (43 of 86 entries), averaging 2.23 copies per deck — so players aren't going full 4-of, but adoption is real and widespread.
The performance split is striking. Affinity lists running Krang mainboard went 80-46 (63.5% winrate), while lists without it posted just 67-65 (50.8%). That's a 12.7-point gap in winrate over the same 11-day post-release window. The sample is still relatively small (43 entries on each side), so treat this with some caution, but the direction is clear: early results favor including Krang. Its Affinity for artifacts cost reduction makes it castable well ahead of its 8-mana base cost, and its enter-the-battlefield refueling effect plus pump scaling with artifacts lines up perfectly with what the deck wants.
Overall, Affinity sits at a 51.3% winrate across all recent data and is well-established in Modern. Krang looks like a genuine upgrade worth testing in multiples.
