Riku is a popular commander, and it's easy to see why. Most decks with him just fill up with powerful spells. I tried to capitalize on his copy ability by using spells with Replicate, Rebound, and Storm so you can get as many copies as possible of your spells into play. If you like it, please leave comments or suggestions and if you wish, leave a link so I can return the favor.EDIT 11/06 (Because change is good):-Temple of Abandon-Temple of Epiphany-Temple of Mystery-Brain Freeze-Darksteel Plate+Alchemist's Refuge+Maze of Ith+Petrified Field+Hive Mind+Crystal Ball
My favorite combos in this deck:Riku + Possibility Storm + anything: Possibility Storm is too much fun not to include, but when you get a great card in your hand, you can't play it. With Riku, you can still get a copy of it into play while triggering Storm's ability to search for a second card.Cast Through Time + 4 Instants/Sorceries + Research (Research/Development): When all your spells have rebound, you normally get to play them only one more time and it has to be done at the beginning of your next turn. With Research, you get to bring them back to your hand to use whenever you want.Rite of Replication + Parallel Lives + Riku + Strionic Resonator: You could have one token. Or two. Or five. Or ten. Or twenty. Or thirty. I chose Parallel Lives over Doubling Season because it costs less and I don't have many cards that deal with +1/+1 counters.Kiora, the Crashing Wave + Parallel Lives + Strionic Resonator: Getting a 9/9 Kraken every turn is great, but how about getting four? That's the nice thing about Strionic Resonator: it works with many other permanents besides Riku, like Animar, Melek, and even Mana Flare.
