I need a Disenchant effect somewhere in white or green common/uncommon.

(This also makes me more convinced that Geasses should be sorceries/instants rather than Auras, because the flavour of removing a Geass is a Geass Canceller and not anything else. The enchantments in the set that this can hit is things like The Ends Don't Justify the Means, Gefjun Disturber, Steal the Prototype, Forgotten Identity, We Have Reserves and Black Knights Hangar, Collective Subconscious and Hostage Situation.)

This is another card effect where the power level fluctuates quite a bit. Forsake the Worldly is better than this; Fate Forgotten is precisely this; Ironwright's Cleansing / Fade into Antiquity is worse; Altar's Light is worse; Revoke Existence is orthogonal. Up at you get this effect with various benefits like Return to Dust or True Love's Kiss.

I have no problem with this being relatively good, as the biggest use case is blowing up Knightmares, and, well, the series does have a lot of blowing up Knightmares.
