Especially Mr. Weevil, or whatever his name is, that plays with three four-star ladybugs of death and three man-eater bugs, and three trap holes, and a mirror force, and a torrential tribute... and haunting echoes, and monster reborn, and change of heart... there's nothing more frustrating than playing against his deck.
Although I bet the opponents I have yet to unlock are worse.
And the game cheats SO BAD. It knows what all your face down cards are -- it'll attack to kill an electric lizard, but won't attack to take counter-damage from a mystical elf.
It's also annoying to get cards randomly five at a time, so that you have to incrementally strengthen your deck by swapping cards in and out one or two at a time, until you suddenly realize that your deck doesn't work anymore.
