I'm glad Grandma's been treating you well, Sumradagnoth! I don't know what I'd cut for Hurricane, but let me know how it goes!

VeggiesaurusRex Granny puts a heavy beatdown on my pod :D

Currently have Hurricane in and Harmonize out
Also added Lotus Petal and Deserted Temple, and pulled a forest and Darksteel Citadel

Sumradagnoth, between Gaea's Cradle, Itlimoc, Cradle of the Sun, and basics enchanted with Wild Growth and/or Utopia Sprawl, running Deserted Temple is a great idea! I need to go pick one up!

I forgot about Ancient Tomb and Nykthos, Shrine to Nyx! I've beem missing out on so much mana!

Since when was fast mana useful?

VeggiesaurusRex Some more of my mods to your list:
Mirri's Guile is out (It felt like just too much with Divining Top, Sylvan Library, and Cream of the Crop) and Beastmaster Ascension is in (it is just TOO good in this deck and great value)
Hurricane is out and Nylea's Intervention is in (more versatile, and more chances to grab stuff like Deserted Temple, Nykthos, or Cradle if I dont need to smash some fliers).

Evaluating Parallel Evolution but not sure what I would sub out.

Again, awesome deck!

Sumradagnoth very cool! I ran Beastmaster Ascension for years but eventually cut it for a couple of reasons, primarily that it can't be tutored for in mono green and that it doesn't grant trample.

And Second Harvest costs less mana than Parallel Evolution and is an instant. I ran it for a while but cut it because it only ever seemed to show up when I had no tokens or when I had so many that doubling them didn't really make a difference. Maybe your experience will be different.
