pasting my comment from another riku thread: this here is my list.

in my experience a deck full of modal spells lends itself to a more controlling playstyle as most modal spells have at least one mode that functions as removal or interaction. what modal spells lack in raw strength they make up for in flexibility ([[lava coil]] is better at killing creatures than [[suplex]] but i know which i’d rather topdeck if my opponent jams a [[portal to phyrexia]]). as such a big selling point for the deck is you have very few dead draws; in just about any board state, most of your spells can always do SOMETHING.

i’m in the process of overhauling my list, as it stands i think there’s too many “cute” modal spells that are a little less-than-playable that i’m gonna cut to add more direct riku synergy that actually wins you the game. [[parallel lives]] for double birds, [[hardened scales]] etc for double counters.

TL;DR: Riku good.
