I really like this deck. I'm still working on my Trostani deck.

Chalice of Life  ^Flip should definitely be in here. If they can't get rid of it, it's going to be a big problem. Even though you don't have too many creatures that do stuff when they come into play, Conjurer's Closet could still help with your life gain. Essence Warden and Soul Warden will also help out with more life gain, then maybe end the game with Felidar Sovereign ?

What about some more populate cards - Growing Ranks and Wayfaring Temple ?

There are some heavier token cards, too - Crush of Wurms and Parallel Evolution . Plus, flashback is great!

Just some ideas. I'm not quite sure if you're more worried about overrunning with creatures, or life gain, but I hope some of these give you ideas.

Thanks for the suggestions. I'll try and give reasons as to why I don't run them clearly.

The life gain cards: The life gain is used strictly to keep me alive and keep me at high life for Storm Herd .

Growing Ranks - I took it out, it's useless if I have no dudes, and there's nothing I'd really wanna take out for it.

Wayfaring Temple - Doesn't have trample. If it did, I would use it.

Crush of Wurms - Sure it makes 3 big duders, but they don't have evasion. At 9 mana I want something akin to Entreat the Angels or Storm Herd .

Parallel Evolution - Same reason I don't use Nomads' Assembly and Growing Ranks , it's not good if I lack creatures. (which is common, because sweepers are a big thing in my meta.)

Voice of Resurgence might be a nice card to put in. Even just killing it off to get one of the tokens makes for a powerful populate tool.
