The upped one is too abuse-able with unupped novas... Grabbows are even more buffed now.
You mean add more cards to a speed deck?
What if I made upped deal 2 damage at 2 
?
Grabbows run a few quantum pillars. If they replace them with this... not necessarily a lot better, but graboids drop earlier. And no, upgrading cards in a grabbow isn't too bad, as it helps with arena grinding. (Bronze/silver, to get SoRs for instosis)
Enough of this OT stuff.
Back to the card, I agree with ZBlader. 3-4
would fit perfectly fine. Increased damage on both fields also amplifies the specialty of this card.
