I can't help but think that Lion's Eye Diamond will whiff in this list. The sac requirement stops you from abusing it with Dramatic-Scepter. Is there another use I'm missing? Solid list, by the way.

LED is pretty spicy in here, I think - it does all the cool stuff that both of the Baubles do (make super early Wheels better, activate Mox Opal, and make it much easier to go off after dropping a very early Paradox Engine), and on top of that, I can always crack it by holding priority before casting a Wheel or something like a Meditate. Just from gut feel, this deck is somewhat bottlenecked when it comes to coloured Mana in some situations, and LED defintiely help with that. That being said, I haven't tested this yet, and I only changed around 5 or so cards from Lilbrudder's list cause I'm considering playing it in a LabMan video at some point. It definitely does look solid though, and it'll probably be a blast to play.
