[Deck Help] Protect the Backline!

Hey guys, so I was working on the Gravitree review, specifically the Sample Deck, and I came up with an interesting concept involving Spudow. Basically, I wanted to run a deck around stuff like Blooming Heart, Banana Launcher, electric Blueberry, as the "backline" while protecting them with frontline like Gravitree, Potato Mine, and Spikeweed Sector.

It's been going okay, but I've run into several problems including:

• Lack of card draw: big problem, I run out of steam pretty quick if they manage to remove my board.
• So many options I don't know what to run! I want to fit in Poppin' Poppies maybe, or even Pair Pearadise, maybe even use Strongberry, or photosynthesizer but I just can't decide. (maybe even starch lord for card draw?)

Any help will be greatly appreciated, here's the decklist: http://imgur.com/BMShXnL

Collection is pretty full, so barring adding x4 legendaries, I should be able to make the suggested changes.
