See, if you arrange the colour pie in linear order, the colour pairs are WU, UB, BR, RG, GW, and then WB, UR, BG, RW, GU
Sliver decks often have some disposable creatures that would allow you to attack as a band and keep the attackers you need alive
I have to say that Im a huge fan of this design as a way to help scale combat damage to the higher life totals in Commander
In the same vein to the formats mentioned above, Quirion Ranger facilitates running lower lands counts and lets us untap Elvish Archdruid for EVEN MORE MANA
While I expect the deck will have all of its colors thanks to the 17 five-color lands, paying a life every time you want to cast something adds up, especially in aggressive matchups
