zilliax is tier 1 when it comes to crafting of all legendary cards in the game. I would craft blastmaster boom since it is a very good card and bomb warrior will only get better as more control cards are added for warrior through the next 6 expansions. Tbh I would not craft anything yet as it is been barely a week if you have to little dust wait at least a week more. I am playing mech paladin right now and I am a rank 2 player bet deck I have tried so far.
Well I'd be damned if I didn't have Zilliax by now haha. I was asking more in regards to the new expansion! And the only reason I hesitate towards crafting boom is because the entire deck itself costs 7k, and the card can only be used with bomb support (future archetypes might not support it). Mech paladin though, interesting. The net-deck looks a bit clunky IMO. What variant are you using?
