I asked because even though i may not have a lot of gems close to 2k, i was hoping for a new blue eyes structure deck with blue eyes choas max and spend my gems on that. That's if it was added in a structure deck.
Brionac is a brutally effective card in this meta but it's a standalone UR and difficult to go through and entire main box for it. Blackening is a very strong archetype but still not at full strength. Expect it to be tiered though. You should however go for a different archetype of you have one in mind because blackening has a lot of UR cards across two boxes that need to be bought to be effective
I did go through half the box of the BW Dragon box. I have 1 spear and 2x Blackwing Flame and amongst others. I do have to check what i got. But since this may have 180/200, i may pass
