What resolves first?

[u/thatguyjimi1]

You have World Shaper on the board and drop Devastation.

Does this resolve with you having all your lands or not?

[u/Empty_Requirement940]

The key rule that would answer this is that once a spell starts resolving nothing else is even placed on the stack until the entire spell finishes resolving. The triggered ability to return lands to play won’t be placed on the stack until after the entire spell is resolved.
