When you planeswalk to The Garden of Apeiron and at the beginning of your upkeep, put a noise counter on it, then destroy all artifacts with mana value less than the number of noise counters on it.
Whenever chaos ensues, when you next cast a spell, discover X, where X is that spell’s mana value. (To discover X, exile cards from the top of your library until you exile a nonland card with mana value X or less. Cast it without paying its mana cost or put it into your hand. Put the rest on the bottom in a random order.)
