excellent first deck. you may wish to limit the number of legendary creatures to make riku more effective. maybe add some instants or sorceress that have grander effects like Fierce Empath Wood Elves Skyshroud Claim or Rite of Replication or Tooth and Nail or Beast Within or Blasphemous Act or other cards like that. that being said i like what you started with now build it up and beat all your friends.
eroineI appreciate the comment I really want Rite of Replication . The ramp you suggest will help a lot too. I do have too many legendaries right now, I was just running out of cards to fill this deck up.
Why limit your Legendary creatures when you can play Mirror Gallery and make ALL THE LEGENDARY!
-MisterJ- thanks for the comment. I really would really love to use mirror gallery but i just feel like i need it to make this deck effective enough with the legendaries. BUT THAT WOULD BE TOTALLY DOPE YO!
I just built a Riku EDH and I have Mirror Gallery just because some of my locals like to play shit like Thromok the Insatiable so I throw down a Phyrexian Metamorph and copy it off for a total of 8 when it resolves so I have 8 Thromok at 120/120 or better.
