I can see the Bone Dragon! Sardonyx?
the top pile in the unboxing. he has two 5 dice attacks(piercing+1-2 and sweeping), a 2 dice zone poison attack which can cause rot on 8+, 1(or 3, but that wouldnt make sense if he is skeletal) armor, and like 23hp, costing 24 mana
edit: looks like on enchantment that starts with AK, so i'm guessing akiros fortune promo. Also a creature starting with TAL or TAK or something, EDIT but it costs 28 mana!
