This deck has a LOT of quanta. Is it all necessary?
Yes, it have a lot of quanta, but I think in this deck is a good think because that means that you play your creatures really fast, and earth creatures have an excellent ratio attack-cost, that means that the game ends soon and you don't stack giant quantity of quanta. Also it is very difficult to have bad draws in this kind of decks.
The deck is simple and effective, and of course it loses against control decks with phase shields or wings but in a race against other rush decks it have the highest possibilities to ensure the win.
