Upwelling Price

Updated 2026-10-07

Upwelling is a 10th Edition rare that prevents mana from emptying from mana pools at end of phase, enabling degenerate mana accumulation in Commander strategies that generate large amounts of mana across multiple steps. The card sees Commander play in spell-slinger and storm-light strategies where floating mana across phases generates significant value. The 10th Edition printing was the final standard core set in the classic black-border style before newer design iterations, giving it collector interest among players who prize that era. The 30-day price window shows no movement, while the 90-day window shows roughly 14 percent appreciation, suggesting a card that was dormant near-term but experienced a meaningful buying event earlier in the quarter. This delayed movement in the 90-day window without 30-day confirmation warrants monitoring to determine whether the gain holds or represents a prior spike now fading. This is a niche Commander utility piece with recent but unconfirmed price momentum.
