It is very susceptible to any early creature control but if you can get it going early enough it can win sometimes within 5 turns.
The strategy is: First turn play all novas you have(you should almost always get at least one because of the auto-mulligan) and a rustler. Convert all light to life early. As soon as you can get out a first firefly, put it out. If you can adrenaline right away, do it. If not, use its light to turn into life and adrenaline it when you can. Now you will produce 4 light per turn = 8 life. Bless your rustler if you fear creature control or if you have no playable life cards. Try to get out adrenalined fireflies whenever you can, then start putting any dragons you have. If you don't have a firefly to put adrenaline on, you can use it on a blessed rustler.
This deck does very well against level 3 winning about 8-9 out of 10 times and can win against level 5, but not at a great rate. It can win in PvP as well as long as you don't get up against very early creature control. I like it because it is fun to play, uses some strategy and is super quick.
