Customs Officer should be Ayur, Ageless Behemoth. Not sure why the importing is messing up on here lately.
Got stuck in Diamond 2 so I decided to go back to my roots and brew up some mono fatties. Went on a good streak to Master's. Feels pretty solid, could probably use some tweaking though. The gameplan is simple; Hard-mulligan for ramp, then ramp into the fatties.
Rhum, First Constructor is WAY better than I thought it would be. By the time it drops the opponent has used up their removal on other units, so it usually sticks. Then you can puke the relics out of the market on the next turn. Works great for breaking board-stalls.
