If you use Control Magic + Perplexing Chimera you gain control of all the spells you want, making it disturbingly hard for your opponent to win. So maybe you should consider Control Magic because even if you draw it and don't combo out with the chimera, it's still a good card.

I'm not quite following how Perplexing Chimera + Control Magic takes all spells.

In order to use Chimera's triggered ability, control of it must be transferred over. Control Magic creates an effect that takes control of chimera (if that's what you're suggesting). If you swap control trying to take a spell, a more recent timestamp is created in the same layer.

If you swap control using the chimera's ability, control magic will not give the chimera back to you if already attached

I appreciate the suggestion and +1 though

Hull Breach is pretty value town with riku out. Glen Elendra Archmage could also be pretty oppressive. I'm a little surprised Boundless Realms isn't in there because it alone can win you commander games. These are just suggestions from my Intet, the Dreamer deck which I pilot to quite a number of victories. Just some thoughts, hope it helps!

Oh and Maelstrom Wanderer . If you play RUG, you play that card.

@Frampypants I already have Glen Elendra Archmage in here and it's fantastic :D

I don't play Boundless Realms because it's 7 mana and I only have 12 basics in the deck, which is likely to go down as I acquire better mana fixing lands.

Maelstrom Wanderer might cascade into random situational spells like Pact of Negation , Worldgorger Dragon , Mystic Snake , or any other number of things. It's a VERY powerful card, but it really needs the deck to be built around it more.

I had Hull Breach in here a while back, though took it out in favor of going more creature heavy to synergize with Garruk, Caller of Beasts and Birthing Pod . I might put it back in should my meta start favoring Artifacts and Enchantments again
