This deck works because supernova+ a lot of litle creatures= win.
In 20 games played againt level 3 I won all but only in one game I could make the combo. In most games, the it would be better to have two elite charger in place of the chimeras. Also I think, that cloak card is a good concept card but it is hard to work, if you draw it erly, it doesn't give you nothing and it is so situational that another damage dealer has to be better in majority of games.
Being said that, I apreciate efforts to try to make decks that work with cards that are not very used because there are plain worse of what other cards can apport to your deck.
