the goblin matchup is favorable, but far from guaranteed. goblins can rebuild with a quickness after wraths. if they have vial they are good to go, even against devastator.
game 2, I was stuck on 3 land for 3 turns, waiting to cast damnation, and ended up having to devastate@2 to survive, and continued to not draw land/loam.
game 3 he had pyropillar+vial and I lost the damage race. this is important bc earlier in the tournament I beat goblins that had pyropillar w no vial, and I won the damage race w grunt.
lesson: if you are playing goblins vs loam, dont cast pyropillar unless you have vial.
