Paste a list to check land count, ramp, draw, removal, and curve.
Commander lists should usually start near 35 lands, 8 ramp, and 8 draw pieces.
Constructed lists care more about curve pressure, sideboard shape, and interaction density.

Format rules, commander identity, and copy-count problems.

See whether the list actually spends mana on time.
