I can only agree, the list is mediocre at best. I mean you run 10 (!) lands (with 24 total) that don't produce colored mana in a 4-color control deck. In round 2 you lose game 3 because of manascrew that could've been avoided by playing 25 land and/or more than 14 colored manasources total.
Standstill looks like it didn't help you at all. You boarded it out in round 1 and 2 and in round 3 when you cast it your opponent gained an advantage... Any thoughts on this or was this also just bad luck?
