Put a last dragon with the price of 2 novas is anything but free, are 3 cards from the deck, with 1 turn waiting I prefer to put a lycanthrope and use the rest of quanta with other cards
That's still a bit one-dimensional. You can still get the original dragon out of any quanta, even pillars so you only need 1 nova for the combo, this means only 2 cards, OP.
Otherwise, you can always use Supernova + the dragon, still only 2 cards, OP.
Edit: the difference between a Last dragon deck and a Shard golem deck is that SoI almost clears your entire hand.
