Hello, i'm so happy to see your deck, and talk a well note, if you want, there is mine. Hope u will find some inspiration.
I'm not a fan of planeswalker, easy to focus and rarely useful at their +1 or +2 and it's not that good in kyler's deck...

This is the way i build it, first i delete all the elfic manadork to replace them by humans manadork, of course it's a little pricier in term of mana but...it fit the strategy.
You got an umbelievable combo between, horn of condor, call the coppercoart and thalia for exemple.
My deck is pretty cheap, it took me 2 years to build it at this price...so maybe you will not find something you like in it.
for each of those creatures.
