Here's a thing I'm very glad they changed: in this version of the story Feroz, with his last breath, asked Serra to leave Ulgrotha, to never tell anyone about what they had done and "to leave "their children" to live their own lives." This leads to Serra's anger preventing her from saving the mortal man from his accident with the apple cart, while in the comic it was grief
The set, on the whole, feels like a love letter of sorts to MTG
Attunement fits this bill, but it combines with Replenish to bring all those discarded enchantments (you were discarding enchantments, right?) back into play in one fell swoop
The difference, though, is that Trumpeting Carnosaur isnt just a six-drop
Raphael, Fiendish Savior I love cards that can support multiple creature types or even a combination in one deck
The legendary artifact card that jumps to mind for me is of course Excalibur, which will circumvent that pesky high mana value, but there are a ton of sweet options you could put in the deck outside of Equipment
