Rousing Chorus

Instant

Untap all creatures you control. They get haste, indestructible, vigilance, and +2/+2 until end of turn.

"Storm clouds, fire and steel! Death from above, make the enemy kneel! Shining armor and wings! Death from above, it's an army of kings!"

POWER METAL!!!!!!!!

Challenge: Take a legendary creature partner pairing (ie: NOT the Kenrith's) from Battlebond. Make a new card that shows both of them on the same card. Don't just staple them to each other, and don't include either of their names in the title.

Train the Weak

Enchantment

When ~ enters the battlefield, gain 1 life for each creature you control with Mana Value 2 or less.

Whenever you cast a spell, you may put a +1/+1 counter on target non-token creature you control with Mana Value 2 or less. If the spell was white, gain 2 life. If the creature was white, scry 2.

Whenever a non-token creature you control with power 4 or greater and Mana Value 2 or less dies, draw a card.

OK, so you know the Ultimatums? From Ikoria and Alara? Make mono-colour Ultimatums. 7 mana of their colour, sorcery (I think) and it does three things that show off what that colour does. Bonus points for making white, and making it not the worst in the cycle.

Celesteel Armor

Artifact - Equipment

Equipped Creature has lifelink, Ward , first strike, indestructible, and gets +1/+1. If the equipped Creature is an Angel, they get an additional +1/+1 and gain, "whenever you gain life, you may draw half that many cards, rounded down."

Equip

Is that good? I think so. Too good? I don't know.

Go to page 111, post 42. No idea what the challenge is, but random chaotic gut-impulse is sending you there to do that challenge. If Page 111 has fewer than 42 posts, find your first post and do that challenge.

By "Brand New," do you mean, "New Character?" If so...

+1: Create a 0/1 Colourless Thopter Artifact Creature Token with Flying.

-3: Sacrifice an artifact. If you do, scry X, where X is the CMC of that artifact plus 1.

-11: Search your library for up to 3 artifacts, reveal them, then shuffle your library. Put one of them into your hand, one of them onto the battlefield, and the rest on top of your library in any order.

C18 Saheeli was my first "real" M:tG deck. My first actual M:tG deck was a mono-white Angel Tribal deck that had a lifegain sub-theme, that me and the friend who introduced me to Magic proxied. He tried to help me, but it was not well made.

That said, imagine WotC posts an Angel Tribal Pre-Con. Make, not the face Commander, but rather, one of the 2 other Commanders you can use, instead (much like Brudiclad/Tawnos in that Saheeli Pre-Con).
