i think if you throw a
vraska the unseen in youll do pretty well with this. once you get her and you get the 1/1 assasin tokens out your really well off. also, it wont matter that they are a 1/1 because you have those viridian claws,
sword of vengeance and other counter related cards. I also think that you should throw some ramp cards in there so that you dont get mana screwed, even though you only need 2 lands to play... but still this can help you with those higher casting cards. maybe some elves? idk, i am brainstorming. also I love your choice of enchantements. if you throw a
vraska the unseen in, with its -7 effect, you can throw in those 1/1 tokens, and then if you wanted to play something awesome like
revenge of the hunted, you win the game! those are some of my thoughts, but i really like what you have here!!! keep it up, and good luck!
