I see conflicting reports on us.battle.net concerning whether or not it is possible to pull the non-golden version of a Promo Card (that is, non-golden Elite Tauren Chieftain or non-golden Gelbin Mekkatorque) from a regular Hearthstone pack. Some people there say yes, other people say no, and I can't locate an official source.
Can this happen, or is the only way to get these (admittedly awful) cards by crafting them?
