And when you can do it repeatedly from the same source

For newcomers and veteran Magic players alike, now's a great time to get acquainted with this set's fresh batch of new cards, mechanics, and draft archetypes

Ive played against it a couple of times in Brawl on MTG Arena, and if you cant deal with Narset before it attacks, it's pretty much game over due to its ability that lets it target non-creature spells from any graveyard, exile them, and cast a copy for free

Whenever a creature you control with myriad attacks, for each opponent other than the defending player, you may create a token that is a copy of that creature to attack that opponent or a planeswalker that opponent controls

It could even be triggered by casting a spell - the spell would say "When you cast this spell, Discover X"
