Thought I'd post what I was playing in my Ezuri deck. It does really well 1v1 and decently in multiplayer (so sick of mass destruction though... thinking about adding Cauldron of Souls and Fresh Meat).
- I've always felt like Elvish Promenade is a 'hold on to' card....but I keep holding on to it waiting for the right time and the right time never comes. I eventually switched it out for Gilt-Leaf Ambush since it can be cast during opponents turn.
Don't know how much use my advice will be, as your meta obviously focuses on the bigger, fatter plays. Never the less, hope you are able to gleen some use of of my comments.
Also, recently came across Tangle. Could be an interesting trick if your opponents are beating you aggro vs aggro...
Another trick that was recommended for me was Vines of Vastwood. Protects Ezuri from targeted removal spells and can even give him a boost if his defense is being threatened.
