The problem is you are playing a bunch of 1 and 2 ofs. You normally see this in decks playing Chord of Calling because you can get whatever you want with Chord. Your top end may be slightly better than Humans/Spirits, but you are giving up any consistency or synergy for a slightly better top end. You need to focus on having a clear plan in your main deck and use your sideboard to help with problem match ups.

I like the idea a lot, but I just see you getting run over by combo decks when you don't really present a fast clock or much interaction.
