Another Homarid Spawning Bed deck. The deck still does fine if the Bed isn't found.
• Creatures that include blue; preferably not legendary (can't copy with Riku); preferably higher CMC (for more tokens with the Bed)
• Cards that can copy Riku without using legend rule (Sakashima, Spark Double)
• Double tokens (for both Riku and the Bed)
• Massive mana ramp (this deck is very hungry for mana). Preferably green sorcery land ramp, as that can be copied with Riku.
