The slow and painful grid deck! Also sometimes referred to as a Millstone deck. This deck is designed to slowly eat away at your opponet's soul. As you counter their every spell, steal their creatures, and shutdown their futile attempts, you grind away at their deck, forcing them to draw and discard until they must draw from a non-existent stack, causing them loose the match. It's kinda sad, but really fun. There are lots of excellent combos in this deck, such as Library of Leng, Ivory Tower, and Howling Mine.
This is a revised version of my Grind Deck. It was a bit bloated and sluggish so I trimmed it way down and kept just the essentials. I modified it from 97 cards down to 66. The result is a much more efficient and deadly deck. You can still view the original Grind Deck v1 here.
