Making a deck full of counter and good stuff shenanigans.

Hey, guys!

Looking for some help with Ezuri. Right now, I'm looking at this list, but I'm finding that it is either losing gas or drawing the wrong cards in the late game as top decks which doesn't allow me to really do anything, especially if Ezuri isn't on the battlefield. I'm wondering what I can do to change this. My maybeboard is full of cards I think would be good to make it a bit stronger.

My sub-themes somehow became both wizards and elves just because the synergy between what I wanted to do and the cards that synergized just happened that way, but I want to keep it.

Hooded Hydra is to stop boardwipes.

Simic Manipulator for stealing stuff and making people hate my deck.

Tezzeret's Gambit for Experience counters and regular ones.

Clever Impersonator allows flexibility.

Heritage Druid and Imperious Perfect help with mana and triggers/going wide respectively.

Hornet Queen helps on defense and offense.

Stunt Double is great for flexibility.

What do you guys think?
