For what it's worth, I still ran 6 pitch spells, in addition to 7 Duresses.

Day 1 I go 4-2-1 and get 20th, playing fairly awfully along the way.

Day 2 I go 0-3 and we go home. Note that in my first match of the day I lost games 1 and 3 basically after turn 1 Duressing my opponent and having them rip Ancestral while I have no pitch magic. Fairly bad beats. Good times though.
