There's probably a weird corner case where you want to have different named copies, but I sure can't think of any reasonable enough to warrant this
Faithless Looting is one of the best ways to rip through your deck and load your graveyard, Vault of the Archangel is a great utility land that offers some impressive keywords, and Gravecrawler is one of the best Zombies ever printed as a result of its ability to continuously come back to the graveyard
You may look at and cast that card for as long as it remains exiled, and you may spend mana as though it were mana of any type to cast that spell. Getting your pick of the top four cards of the best players deck is always a good thing, and because you can cast it even if Gonti dies, it makes the whole thing highly profitable
To determine the total cost of a spell, start with the mana cost or alternative cost you're paying (such as a flashback cost), add any cost increases (such as kicker costs), then apply any cost reductions (such as that of Lyse Hext's second ability)
