You should really think twice about adding some lands. If you haven't had mana issues with 27 lands you are the luckiest man alive. 38 lands with 8-10 ramp spells, and I still get mana-boned sometimes.

Yep, you definitely need not lesser tha 36 lands, i also suggest to you or to change the general, or to put away some fat creatures in favour of cards like: Mobilization card:Cathars' Crusade Sacred Mesa Wurmcalling Gelatinous Genesis you have too few token spawners in a deck with Rhys.. if you need some more ideas you could check my deck with Trostani's Gang in this deck i often interchange the general from Trostani to Rhys..

Rag_90: card:Cathars' Crusade is already in there. I really like Mobilization and Wurmcalling . I've never seen those before. And I'll definitely take a look at your deck! Thanks!

Looks like an awesome build. You might want to throw in a Seeker of Skybreak so you can tap Rhys more than once a turn, also mana ramp might be a good idea since your spells are pretty expensive and any excess can go to making more tokens. Have a look at this deck for some ideas Elfball Highlander

Samwise9787 I'm gonna be adding Wirewood Lodge and probably a Thousand-Year Elixir . I think the mana ramp in this deck is pretty solid so far with Fertilid , Knight of the Reliquary , Harrow , and Primal Growth being at the forefront.
