Thanks for the tips, I was thinking since I've seen quite a bit more 3 color decks than I thought there would be in the new standard, does anybody have any suggestions for which color I could add?

White is the obvious choice for things like Declaration in Stone, Anguished Unmaking, and Dragonlord Ojutai. If you look at the Esper Dragons list that won the GP recently it'll give you an idea of what that looks like. Running white will likely replace your counterspell package, though.

Sounds good to me, removal is more relevant than counterspells in the current meta anyway

Maybe you could play one or two copies of Felidar Cub in case of tutelage and other "annoying" decks.

More than half the deck misses on a Narset Transcendent plus, and 9 of the spells don't work with her minus. I feel like a different planeswalker would be better, like Sorin, Grim Nemesis.

When I used to play esper dragons I threw a litte bit of tokens in there just in cass I Would get a litte stuck! So I would suggest maybe a Gideon, Ally of Zendikar and or 2x Kalitas, Traitor of Ghet into the main board, especially with the removal! Dragonlord Silumgar is good but I don't think 2 is necessarily worth.

I ended up basing my current build on this article I found online and have unfortunately yet to give it a test drive. After seeing how the Kalitas' do in the sideboard I may keep or move them later.
