Come on now,
abrade isn't that
dangerous. If used on anything worth 3 mana or less then the player using it is either losing out on mana or at it's best stalling the game for one turn. It's really only useful on artifacts worth 4+ mana and due to its versatility.
Speaking of treasures and
mechanized production, it will only stall your win with one turn (a stall worth 3 mana). I think you've come up with a pretty neat idea, to combine it with treasures. Speaking of which, it prolly works just as well with servos/thopters.
Cheers!
