Missiles and wave are actually played. Firework is really bad, first you need to play a 6 mana card at least in order to corrupt the elemental, then it deals damage to a single target... in an aggro meta. Even against druid that plays big minions is not enough cuz they usually fill the board and killing 1 minion doesn't help. Oh my yogg is anything but a win condition, the effect is random and sometimes can help opponents, top decking it in late game feels awful, paladin already has enough big and sticky minions, doesn't need that secret to protect them. It could be good only if some type of aggro pala becomes meta but pure and broom are just too good right now.

I don't know exactly what Tekahn+ Polkelt+HoG means. The 5 mana 4/4 that makes lackeys into 4/4s + polkelt + hand of guldan (I assume that is the card)? If this is the case then I don't see how it could be an archetype. You need lackey generators, paying 6 mana for hand of guldan is not worth, at least with skull you get to discount the cards drawn.

Cult Neophyte comes down earlier, it also fits better in turns where you spend mana on other cards. If the other minions are still vulnerable to AoE I don't see how robe is control's nightmare as they usually run several AoE cards.
