No, the JMB is not allowed.

I understand the JMB is not allowed on standard but i tried a few times on claire b hardcore and i don't see a chance to defeat G4 with just quickdraw and sls. maybe i do something wrong idk.. did someone test it already if its possible?

Have u read the rules? It is allowed. Though there is mistype. It reads as JMP. But I think it is allowed.

This forum is almost a year old. At the time it was not allowed

Oops sorry I didnt notice. Thank God it is allowed
