Aside from being a human, which is a very relevant creature type in Commander, Modern and basically every other MTG format, Esper Sentinel is good because it reads: Whenever an opponent casts their first noncreature spell each turn, draw a card unless that player pays X, where X is Esper Sentinels power. Its a bit like Rhystic Study, but the cost can be far higher if youve got things that make humans stronger or you can put +1/+1 counters onto Esper Sentinel
Cards like Marionette Master and Disciple of the Vault are great at this, making your opponents lose life anytime an artifact goes to the graveyard
You can pay two loyalty to get an emblem that gives all knights you control +1/+0 and ward one
However, she can quest for two in addition to some of her stronger abilities, such as being unable to be challenged by other pirates in Disney Lorcana and giving all other characters being challenged Resist +1
Early calls, but it seems like there's a lot of good stuff in this deck
