This is my first speedbow, seems to work very well for pvp2, Top50 and Half-Blood.
After loosing a match against a speedbow with a Hourglass I added one myself and it proved very usefull when I got it. Only one Explosion as I wanted to minimize cards other than creatures, helped me a lot to get bucklers or hourglass down.
I saw lot of speedbow with precog but I don't really see the use of it: seeing your opponent's hand don't help THAT much since I don't have much control anyway, drawing another card is cool but I would still need time quantum: what if I got several precog in starting hand and no time quantum already? thought it might be better to stick for only creatures.
Any suggestions to improve?
