"Fantastic Beasts and How to Get Stomped By Them"

This deck is meant to get big creatures out, fast as all get out, and control the board until they do with removal spells. I already know this isn't nearly as efficient as it could be, and that it is very weak against heavy-duty control decks. Any way I can tweak this and make it more streamlined and versatile?

Thank you in advance. I really enjoy learning more on this site from everyone. I'll be making edits as they are suggested, depending on if I have the card or not. =)
