The Time Stone. Duh.

Reality Stone for sure

The darkhold!

Jk, jk 😂. I would probably want Sam’s falcon wings or T’Challa Black Panther suit.

The Yaka Arrow and Stormbreaker/Mjolnir

Mark 42 suit and Coulson's hologram shield

Either Stormbreaker or Yondu’s arrow (forgot it’s name). Time Stone would also be pretty cool
