You can find other recent set reviews here: Card Kingdoms set review only cares about broadly relevant cards, because we want to maximize the usefulness of the cards in your collection
Brightglass Gearhulk certainly has the stats
Its the Silverquil (WB) mechanic Converge If you cant decide what college to play and want to go all five colours, Converge is the mechanic for you, providing a bonus for each colour of mana used to cast the spell Flashback Not much to say here: Flashback, one of the most beloved mechanics of all time, returns here for the history-loving Lorehold

Some include a physical or vocal component, like Blacker Lotus or the Gotcha! mechanic on Touch and Go, some have rules that specifically reference flavor text or artists, like Carnivorous Death-Parrot and Drawn Together, and some require interacting with people or objects outside the game (Ashnod's Coupon being my favorite)
