So we've now officially confirmed that Hero skins do not affect cards anymore, which means....MECHA JARAXXUS AS THE SECOND WARLOCK LEGENDARY, LET'S GO
Also, this isn't half bad. We have Astromancer, unexpected Results and probably something else I'm forgetting right now. Why not a control oriented (Hand-)Mage that excels at summoning big stuff later on while controlling the board early....also double Ragnaros.
Don't forget, there are very few infinite Value cards out there anymore, so overwhelming people with big dudes is not that bad.
