Feinting Feint makes Doremy not deal any attack damage and covert it to Nightmare instead. It should not deal damage to block or barrier and I fixed that, thanks.

There are a couple of issues with Doremy but the biggest one is that if the true culprit has 300 or more Nightmare you CANNOT DEAL DAMAGE DIRECTLY, meaning you have to deal damage exclusively through capping that nightmare (damage does work normally against barrier), i had specifically a red card that adds nightmare equal to attack damage and it didn't trigger as well, that might have caused the issue
