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
Taking an extra turn as soon as she's cast means she has pseudo-haste, and annihilator 6 can typically decimate most of your opponent's board (quite flavorful if you think about it)
The ultimate is quite easy to pull off with Sorin growing so effectively and protecting himself well and gives black a lot of ways to deal with things it otherwise struggles with by using your opponents cards to get the job done for you perhaps with a Disenchant they handily had for you
It's a small value engine, but it is definitely not among the most powerful artifacts in the game like Black Lotus, the five Moxes or Time Vault
If we have a mulligan, were allowed to take that chance twice
D&D and Magic go together like peanut butter and chocolate
