mtg kaalia of the vast commander deck (Heavenly Inferno) you may put an Angel MTG Proxy Ready-to-Play Commander Deck:

Amethyst can always be improved with the Bounce package of Merlin and Madam Mim characters

Following up Pinnacle Emissary by casting a bunch of artifacts and flooding the board with Drones also has some appeal, especially in formats where Mox Opal is legal

The equip cost for Planisphere is rather small, as well, allowing players to reequip the Planisphere to anything, turning them into massive potential threats

The Treasure Planet card opens up a whole wealth of opportunities for players, allowing them to take advantage of the cheaper cost of Shift cards - as well as their impressive abilities - without needing to actually have the less powerful cards needed in their deck

Use the cards you milled to escape the Diamond, which you use to cast Brain Freeze again, and so on and so forth, until there's enough storm copies of Brain Freeze to mill your opponent
