How it grades
Fundamentals 77/100. Plays like Artifacts.
This reads as Artifacts, built around Osgir, the Reconstructor. An artifact engine deck: cost reducers and cheap trinkets snowball into board states and card advantage that scale with the artifact count itself. The pieces are individually weak but the whole is far more than the sum, and a single well-timed Vandalblast is the scariest card in the room. Its strongest fundamental is ramp (16 ramp effects (want 11+ for this curve for Artifacts)); the first thing to tighten is mana curve: 21% of spells cost ≤2, 23% cost 6+.
