I feel as tho for some missing that require you to get a quick victory against an opponent at level 30 are to hard for people who are free to play such as myself. I feel as though the quick victory should be extended a little bit to atleadt did turns or at least remove those missions or if not remove the level 30 marker because It makes things difficult to have to get 3 quick victories against an opponent at level 30. Especially if their deck allows them to continuously summon monsters
