Can someone explain to me why AI won't attack Noble Knight Drystan, my defense deck lost a duel by deck out because my monsters refused to attack Drystan.
lol, that would suck. The only bug I've encountered personally is when the AI is using Water Dragon and uses a Bonding Spell but will only tribute 1 monster of the 3 necessary and still summons WD.
have you read Drystan effect?
if they have 2 on the field you can't attack either since Drystan effect states you can't select a target to attack with less than 2000 atk. this is virtually like dyna where you get 2 on the field and you can't atk either.
I thought they both had to be under 1800 ATK. If Arfeudutyr took them both down 500 then it's viable. I haven't read it on DL but I remember the cap being 1800.
