In a Burning Wish list like that with LED, I kind of like 2x Gamble better main deck than the 2x Faithless Lootings. A lot of hands are just missing an LED or a Grisel in the yard to be explosive. And I think a 2nd Unburial Rites fits better than Reanimate. Reanimate is still worth the wish-slot as the cheapest reanimation to cast.

Grave Titan is definitely worth a slot. Good to have a non Karakas-able creature in the main with the amount of DnT around again, and like you said hard casting him isn't that hard.

I used to like having 1 or 2 Simian Spirit Guide as extra fast/red mana, have you tried any? Could Past in Flames be worth that wish-slot over Gamble?
