I've tested many cards in the deck, including silklash spider, defense of the heart etc. Currently this is what I have found to be the most optimal.
Cards that could be replaced or that I tend to swap are back to nature, mirri's guile, sol ring, and Nylea. Its a good 1v1 and multiplayer deck. I've had upwards of 58/58 lands with trample swinging for lethal. My favorite card in the deck though is Predator, Flagship, love that thing! Thanks for looking!
