I don't think so. You still have 40 life!
Man, you are one mana short of really depleting your hand, if I'm counting correctly. It would have been great to cast both the Hydra and Duneblast, but even with the Plains in your hand, that's only 11 mana when I would need 12. Bummer....
So here's what I'll do:
Plains
Kalonian Hydra
Remove a ctr and create Saproling from Ghave
Use Ghave to sacrifice all of your creatures and put ctrs on my Sangromancer, saving Ghave for last and gaining 15 life
Done - I hope I did the best I could with that
My turn - draw, so my hand is:
Kydele, Chosen of Kruphix
Grave Upheaval
Fellwar Stone
