Grindstone (PRM-62423 foil) is an artifact promo from the Magic Online Promos series. Its activated ability causes a target player to mill two cards and repeats whenever the two milled cards share a color. Because of that repeatable interaction it supports combo lines and deep library disruption when paired with ways to repeatedly activate or recur it.
