Earthbound Immortal Deck Help?

Love your deck, it's pretty much set to go. Maybe you could get a couple more Wiraqochas and Swallow Nests, it could actually be an OTK. THe only thing I don't like about Wiraqocha is that you should be good at swarming, so you could tribute 3 monsters rather than your back row that protects your field spell/E.I.
