When the 6 cost creatures are transformed by orosei, there is less variance regarding the 8 cost creatures they can transform into (colossi, icerock giant, baeru, ignus, or battle ogre).
Egg of wonders can transform into your 6 cost creatures. Forbidden library helps pull out cards for the orosei combo and also help flip your eggs. farmboy is a cheap collector to compensate for the naturally high faeria cost of the deck. The guards are also good collectors, defenders, and faeria gain and draw power. Emperor's command can be used as a flexible tool to kill your own library or heal against rush/burn decks.
Wavecrafter is interesting in that it messes up with combo decks which are starting to become prevalent in ladder. It can also set up a combo of your own if you have failed experiment -> stormspawn and orosei in hand. Just +1 when your turn begins again to get 7 faeria, then with the FE->SS get to 10 fearia, then boom orosei.
Mulligan for farmboy, queens/kings guard, library. Build lakes defensively. Only create the 3rd and 4th lakes when you have wavecrafter, egg, or library in hand. Otherwise, prioritize solidifying your defensive land triangle. Against control decks that play slowly, you can afford to build up one side immediately to secure some aggressive lands.
Note that this has been only piloted twice in Casual and both were pub-stomps. Please let me know how it works out for you and what changes you would make. Have fun :D
Edit: Switched out Farmboys for Sturdy Shells, 1 less egg for 1 more Emperor's command.
