Since Zirda, the Dawnwaker only cares about permanents, it could show up in a deck that is mostly (or exclusively) spells (people have mentioned this as a possibility in Vintage, where some decks incidentally meet Zirda, the Dawnwaker's restriction, although whether or not getting a random 3/3 in hand to start the game is worth a sideboard slot remains to be seen)
Contained within the Amethyst/Steel Starter deck is a new Lorcana theme from Rise of the Floodborn called the bounce package
This action doesn't use the stack and can't be responded to
Artifact Board Wipes (Hurkyls Recall, Rebuild) Generally, I dont love mass bounce spells for artifacts in Commander
Keep an eye out for special appearances by fan-favorite monsters Mothra, Rodan, and Hedorah
When this legendary artificer enters the battlefield, you draw a card for each artifact you control, so its a huge payoff in token-heavy builds
