Really good start. I've been playing a similar list to really good success. I would find a way to add 4x Fortify. It's absolutely a blowout against most decks as well the much need reach we lack. I would also cut loyal Pegasus in favour of cavalry Pegasus. It's just that loyal is a really bad 1 drop for this deck. Ajani caller of the pride is also amazing as a 1-2 of if you have him. I've gone ultimate a bunch of times against esper and uw. Have fun romping over people. I have.
