Bloomburrow itself is a very two-color centric format, with some slight splashing, so doing more gifting of treasure would have been hard to pull off in such an environment
Their actual rarity varies
The Modern Horizons 3 Creative Energy Commander Deck includes 1 deck of 100 Magic cards (2 Traditional Foil Legendary cards, 98 nonfoil cards), a 2-card Collector Booster Sample Pack (contains 1 Traditional Foil or nonfoil alt-frame card of rarity Rare or higher and 1 Traditional Foil alt-frame Common or Uncommon card), 1 foil-etched Display Commander (a thick cardstock copy of the commander card with foil etched into the cards border and art), 10 double-sided tokens, 1 deck box (can hold 100 sleeved cards), 1 Life Wheel, 1 strategy insert, and 1 reference card.
Look for a commander that provides: Mana assistance (ramp, cost reduction, or cheating Angels into play) Protection (hexproof/indestructible-style effects or shielding key threats) Lifegain synergy (payoffs that reward steady life gain and stabilize races) Thats the common thread behind the best Angel commanders in MTG : they make the tribe feel consistent instead of clunky
Of course, we all know that Release to the Wind is actually played to exile manifested Time Stretches to cheat them out for free, and Soul Partition aims to fix that by making its owner pay full price for the spell again, with an additional as tax for opponents
