I played raid card on opponent and took away his elder sign artifact. Next turn, I played a spell attack that should do 7 damage. Opponent's 1 elder defense blocked all 7 damage. Broken.
When computer plays dimensional shambler card, it's broken. If player's elder defense is 1 or more, dimensional shambler doesn't attack even though it ignores elder defense and would do damage. Probably a function designed to save time by eliminating 0 damage creature attacks, but should not apply to dimensional shambler.
