I like the concept draco - interesting, cost effecient and not OP.
However with only 4HP it is very vulnerable to CC and will likely die before it can use its ability.
Considering that fire rush decks are among the fastest in the game - it is likely too slow for a rush and too vulnerable for a stall. I'd suggest either reducing the number of turns that you wait or, change it so that any death triggers its ability. It opens another possibility, killing your own creature for a faster rush, and while that costs card advantage it is already a common fire tactic. And like Phoenix makes the creature largely immune to CC.
