I do run this Warp World deck with my casual playgroup and I just figured the synergy that Dryad of the Ilysian Grove would add to the deck. The question is what to cut...
My first thought was to replace Khalni Heart Expedition, but it can fuel a faster Warp World when played early on. Then, I thought cutting the Oracle of Mul Daya, since I don't have any way to control my top deck and that Courser + Dryad would kind of provide with the same effect. Then, I thought cutting the Courser, but it provides a good body early game and the life gain can help against aggro deck.
Without playing the deck and getting a feel for what makes a difference in games, this is a tough one. You have so many 4-ofs that you could consider dropping a single card from, say, three of them, then fill in with Dryads. After several games, maybe you'll have a better feel for which synergies are most important to keep.
I realize that's kind of a copout answer, but I'm afraid I'm not familiar enough with seeing Warp World in action to have anything better...

What would you cut?
