Looking to play this deck competitively. Have been playing at my LGS, with positive results. However I am currently working on how I should proceed with cards on maybe board in regards to the meta in a more competitive scenario. Have also considered looking into purchasing the additional cardw to build into a Bant Spirits, but the cost for those few cards is quite high. So I feel favorable to remaining blue/white. Link to decklist is below.
