So all card are 2 mana or less meaning with those 2 apprentice your spell are free
so the otk is;
2 apprentice + Luna + any spell
the dps for the otk will come from ignite because when your deck is empty you still have those 2 ignite that go back to your deck & cycle each other with luna
why quest? It is a draw, dawngrasp is useless to us (except if you roped he is kind of a finisher)
you could remove all spell that require a minion to target with stuff like arcane missile
card to replace are:
First flame & Ray of frost
primordal glyph & magic trick (because they could clog your hand with ‘´expensive’´ Spell
