I would also consider, as long as you're breaking multiples and doubling fetches, to go with more Brainstorms and fewer (possibly none) Preordains / Ponders.
my beef with the Red Deck in the modo cube (as i've typed before) was that it was underpowered and had a joke of a curve but would often win due to opponents doing nothing before turn 4 and/or being color-screwed. Wadds, are you saying your beef is that it's a "distinct archetype" as opposed to just another stripe of aggro (or R/x aggro), because those kinds of decks aren't supported? a friend here has a power cube, he once said that he observed a strict distinction between "mono-red" and "boros" as archetypes, which seems like stinking thinking to me.
If there were two drafters in monored you both had shit decks.
basically i think in Cube tempo decks are not possible to recreate, unless you're willing to make an enormous design concession to their uniqueness and run ~15 cantrips + ~4 delvers + maybe some nimble monguises. blue aggro on the other hand ... who knows. the difficulty is that devotion would make the deck mainly U but then you'd still have to have another color. UR and UB are easy enough to imagine as counter-burn and zombies, but what would UG and UW look like?
