Below is my list for Wrexial. This is NOT a mill deck. It is part-discard/part-stax and wholly annoying for my opponents. It has many small little combos but not necessarily for winning or anything. Mostly for locking the game down until I can beat opponents slowly with tokens or kill with Psychosis Crawler after chaining a few windfalls with a waste not or geth's grimoire(Necronomicon). Honestly, the most common win-con is scooping. Playing commander against Wrexial is like playing Call of Cthulhu RPG, everyone either dies or goes insane. Nobody wins.
This is just a working list, I am constantly switching cards in and out trying to balance the discard, removal, mana denial, and actually being able to end the game.
