Shadowverse

I don't know, I think Miracle Rogue will still be viable, even if it becomes weaker. Yes, it will be harder without stealth, but: Reno goes to Wild, Freeze Mage in its classic form goes there too, Warrior loses Marin, Pirate Rogue gets nerfed – so, of the dangerous opponents, only Jade Shaman remain. And maybe some Face Hunter/Zoo Warlock, if they appear in the meta. Although, this is all just theory; they'll release new overpowered cards, and everything will be turned upside down.
I crafted Ragnaros back in the day, as well as Sylas and Azure Drakes; it's a shame. But I never got to play Freeze Mage, lol. No Alexstrasza.
