New Miniset is... strange so far

The recent miniset is kinda weird just to put out there, it really shakes up how you need to build your decks.
So far, i’ve found good success with a Protos priest deck, and i’ve seen Death Knight utilize their Zerg cards to good effect too. I think Zergling is a really good replacement for Mining Casualties, and Viper is really strong right now and might get nerfed as people are complaining about. Not sure about putting Horseman + Kerrigan hero cards together though.
Terran it seems is the weakest because i just haven’t seen anyone using it, i’ve tried to understand it but I’m unsure of how it’s supposed to work, considering you discount the starship so i guess you need to spam launch them? Not sure.
It’s just a weird thing to do right now, considering most games are decided before round 5, having all these cards pushes deck building in a slower direction, I guess they want to stretch out playtime?
