Glorious Protector
Creature — Angel Cleric
Flash
Flying
When Glorious Protector enters the battlefield, you may exile any number of non-Angel creatures you control until Glorious Protector leaves the battlefield.
Foretell {2}{W}
This card is absolutely bonkers. You’re going to play it in every White deck you own, Foretell it away safely in the early game, and when someone unkind person wipes the entire board – probably you, you’ll flash it in for 3 to save your creatures.
It’s hard to think of a White deck that wouldn’t want this, and don’t worry about the Angels that get missed in this particular rapture; God’s second-favourite creations can always look after themselves.
Search for Glory

Search for Glory {2}{W}
Snow Sorcery
Search your library for a snow permanent card, a legendary card, or a Saga card, reveal it, put it into your hand, then shuffle your library. You gain 1 life for each {S} spent to cast this spell. ({S} is mana from a snow source.)
Ignore the ‘snow’ part of this, and pay attention to ‘search your library for a Legendary or Saga’ bit. This is not quite Demonic Tutor, but it’s close, and the life gain is just gravy.
As I remarked here, Searching up cards changes the fundamental challenge of MTG’s variability, it is the thing everyone needs to do, and being able to do it in white is a big deal.
I suspect this will go overlooked by many, but provide outstanding value to those who use it, because if you’re playing multi Brawl and you can’t think of a Legendary card you want from your deck, then either
- you’ve gone badly wrong with your deck building, or
- you’ve already played them all; you lucky, lucky thing*
Doomskar
Doomskar {3}{W}{W}
Sorcery
Destroy all creatures.
Foretell {1}{W}{W}
Board wipes are something of a signature move for White, and it currently provides Shatter the Sky, Realm-Cloaked Giant and Ondu Inversion, so there’s plenty to choose from.
But Doomskar lets you spread the cost of your wrath with Foretold, which is a bonus likely good enough to see Doomskar played in other formats as well as multi-Brawl.
What’s not to like? If you’re in White, you’re playing this.
Starnheim Unleashed
Starnheim Unleashed {2}{W}{W}
Sorcery
Create a 4/4 white Angel Warrior creature token with flying and vigilance. If this spell was foretold, create X of those tokens instead.
Foretell {X}{X}{W}
Another card that’s good enough when played from hand but fabulous if you can Foretell it first, Starheim Unleashed lets you choose how much mana you want to sink in to it, and when is the best moment to do so.
It’s an outstanding card that we’re already seeing in most decks with White, and looks like becoming a White staple through the next rotations.
