Theres actually tons of cards that are really cool, but not really up to snuff in todays world
This helps make use of cards like Kor Spiritdancer and Light-Paws, Emperor's Voice that want to suit themselves up instead of your commander
Dark Confidant, Aether Vial, and Howling Mine are examples of cards with triggers in one of these phases, and can therefore affect how players wish to interact with them
Magic has a long history of decks built around casting free (or very cheap) artifacts, so theres plenty of precedent we can look towards if we need tech to go all-in on Saheeli as our energy battery
I also feel that Genesis Ultimatum has no Red either, it draws and puts permanents into play so it's Blue and Green
Four fun playstyles with unique commanders in a bundle that makes them much more affordable
