To be fair Super Rush itself would still fail if the attacking monster attack is lower, the bug only works if the attacker attack point is higher, which is hard to top a 2500 atk monster, therefore its not really that significant in my opinion.
I think there is a bigger problem with Toon Kingdom. I think they nerfed it for the tournament. And that means they will nerf it soon in regular game. Some commentator said it was explained to Dkayed and he still picked a toon deck. never should have done it
