mtg mill deck commander The Mimeoplasm A Guide to Mill Decks

10 Ruin Crab Ruin Crab is a great addition to any mill deck as a great defender as well as a source of milling

and because most of the creatures in the deck are Soldiers, making Cavern of Souls into a powerful untapped dual land

It can go after opposing creatures, which means that in addition to helping you blink your own stuff, you can use it to temporarily get rid of a blocker

Its art and phyrexian mana add to this effect, and it makes for a somewhat intimidating card that you cant help but desire to tap into

Sure, this is a good swing late game card but it is so useless against so many lists and in the all important early game that it is a pretty bad option in anything bar a sideboard
