Played a few matches 3v3 blitz mode. was pretty fun… its alot like TC Endwars except that you are limited to sharing resources AND playing cards that are randomly drawn from a 4 card hand from a built deck of i think 20? Like said before not sure how leveled decks will be balanced… since you can buy packs to level up cards and get rarer units. Best thing about this mode is the matches are VERY fast… none lasted longer than 6 or 7 minutes. The one blitz map resembles a moba design with lanes. Awesome part of game is I love how you can get to huge powerful units pretty quick… and matches can counter fast with the right units played.
the beta is definitely worth checking out, on win 10 store. i can see blitzmode as a good casual quick rts… akin somewhat to Clash Royale.
