Card Advantage Card advantage basically means having more cards in hand than your opponents

I just think the card is well executed it being an artifact plays well with Urzas Saga, Improvise and Springleaf Drum, and unlike Thalia, Guardian of Thraben where youre locked out by the tax, you have the choice with Esper Sentinel which presents interesting in-game decisions as you have to balance the tax on the mana versus providing your opponent with card advantage a similar decision to that of being on the play or on the draw

Which, to be fair, is still nothing to sneeze at
