Trading away shiny Mewtwo

As you can see, I'm trading away a shiny Mewtwo. What I really want is a shiny Cresselia. If you have any other offers, please tell me.

how about a shiny ho-oh for it

I can trade Shiny Dusknor,Shiny Mespirit, or Shiny Marshtomp.

shiny fearow, wingull, porygon, golem

I have all the shiny legends except the 3 birds, Cresselia, Azelf, Uxie, Kyogre and the Regis. I'll only take non legends if there are more than one. If anybody offers a shiny Cresselia, they will have the trade.

Nature/level of Mewtwo? It's not worth a shiny Cresselia since she is more harder to soft reset for. :/
