Sky Swallower, Mistmeadow Witch

[izik99]

In commander (where you'd have enough mana to do this) could you exile all your creatures with  {Mistmeadow Witch} and then play {Sky Swallower}, giving them control of only lands, then have your creatures come back?

[Keyeto]

As long as you do it before your creatures come back, yeah. You're good to go! That's some serious mana though lol

 {Legion's Initiative} would work better. Only two mana in a USA deck RW and the sky swallower gives them your lands. But why would you want to do that?

[MuggyWuggy]

You should board wipe non land permanents, tap land for the dude, tap extra mana before it resolves so you can play a mass return to field play AFTER it resolves.

They get nothing, maybe land depending on your wipe spell

[Firemind]

If you have it {Sudden Disapearance} would work well in the same manner.  Also you could play it before or after sky swallower's trigger resolves.
