ATTENTION PLEASE!!! My opponent was using Masked Hero deck with one D.H. Decider on his field. I locked his spell/trap cards with fire formation spells and then summoned three hazy flame sphynx. When I started the battle phase, I couldn't attack! The same thing happened the next three turns! When I tribute summoned Brotherhood Coyote and the attack worked, my opponent surrendered! Is this a new mod? Or I missed some effect?
P.S. the opponent didn't play any other card except that Decider, and he kept skipping duels thinking that I might think that there is something wrong and surrendere.
Please read cards.
D.H. Decider CANNOT be attacked by your level6+ monsters, hazies are lv6, cant atk, Coyote lv5, can atk, he had no answer, he lost, gg surrender
All of this is why decider is one of my favorite cards! 1. Big monsters hit a wall. 2. Revive monsters for back-up fusion material and to get Anki out. 3. One quick save from a lava golem burn.
