know their rules, but if you start winning make up their own. My friend and I were dueling and once my sacreds started winning he tried to ignore the ruling that DW lightning doesnt work if the card is activated in response(because it's no longer face down) so I gave him the link to the ruling and he ignored it. Then I used honest for game and he said he "heard from the guys at the tournament that that doesnt work" I told him it did and I read him the effect out loud and he ignored it. So he went on and said "when I played your game it didnt work either" which made me think to myself "when did you EVER play my game? Let alone with a light deck!" So I won but he wont admit it(its unrated so I dont care too much)
