So Kabal Courier...
Good card or bad card?
I am leaning towards good card right now but not quite good enough to see consistent play. I vastly prefer it over Kabal Chemist though, mostly because the randomness is less and the 3 mana slot is less crowded for the Kabal classes.
I started the expansion playing the card a lot. Then when it time to refine the deck some more to fit the meta, that's the card I ended up removing first. Not that it was bad standalone but it didn't fit against the meta and I needed room for more anti aggro tech in Renolock.
Also Kabal Courier plus Bran... nice.
courier can get you a second kazakus
or let you pull your first one in arena (clutched me a game pulling kaz, sitting on it and eventually getting a 5 mana spell)
so uhhh, rank 18 > 9 with midrange shaman the past 2 or 3 days, have lost twice with it. i've just seen my first pirate warrior in that streak and have barely seen any aggro at all, sans a couple of shamans. everyone is playing anti aggro and MRS eating it alive, esp the jade garbage, priests have been the most common class and they just can't keep up most of the time and azure drake wrecks dragonfire. very easy deck to slide into single digits bc everyone below 10 is playing anti aggro and all the good aggro decks are below that already.
aggro shaman is a very tough matchup , wish i had a second lightning storm in my deck when i play them but having the late game just lets you win against those control classes that aggro can't do as well i think
