The reason why today's shop is the fastest shop in the history attributed to the multiple restrictions in the past few years.
People were whining being locked out and could not play magic. Lock pieces restricted. Now shop becomes an affinity comparable in modern, and now it is complained too explosive.
It is unbelievable that modern can handle affinity but vintage cannot handle shop, given shop can rarely tax you from playing any hate cards like energy flux or Huryl's recall or likes. Or, are blue mages so uncomfortable to pack more removals instead of pyroblasts?
I understood some prefer blue vs blue all the day like in legacy, but it is vintage and kicking shop out of the top tier won't make the meta 'healthier'.
