A midrange deck with a theme around iris barrier,  naga give you some aoe damage vetruvian usually lacks  and healing through herald and aymara is great as your opponent often needs to trade their board into sajj to clear the artifact. In World Cup Reader was banned but if you want to play it it would make the deck much better, i would remove 1 blood of air and wind stricker for them.  The wind strickers are really great but they do make meta meld less consistent.
