mtg mom collector booster box Magic: The Gathering March of The Machine: The Aftermath 10 double Collector Booster Box - Strixhaven:

Ulamog, the Infinite Gyre 8 The poor mans Eons Torn

Also remember that some powerful cards were printed as rares because the mythic rarity didnt exist at the time, like Ancestral Recall, Timetwister, and Time Walk

After Ether's ability resolves, the next instant or sorcery spell you cast that turn will be copied whether or not it has targets and whether or not you spent the mana added by Ether's ability on that spell

Like Deadly Dispute, Showdown of the Skalds will be a key draw spell in its colors until it rotates, simply due to its raw power

Of course, Magic adds new game mechanics to practically every release
