Like most Magic: The Gathering cards, the value of Wrenn and Seven depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Duskmourn: House of Horror Commander)
Scourge of the Throne is a $12 flying beater that brings back the Dethrone effect from the draft-only Conspiracy set, getting stronger when it attacks whoever has the most life points
That design choice earned Teferi bans across multiple formats
Aang, Airbending Master (TLE) $14 Aang, Airbending Master is a strong addition to blink decks, because each creature you blink gives you experience counters and thus more ally tokens
Does it really matter if those sorts spend silly amounts for a textured foil or a flashy alt-art
I certainly dont see Lorcana cards taking over recess like Pokemon did (and still does)
