If you have checked the coverage of the recent Mythic Championships, you’d notice the three Simic Flash decks in the Top Eight. It was probably the most efficient deck in the metagame though it failed to grab the trophy and title of champion of the tournament.

The deck upgrade got some similarities of that of the SImic Ramp version with a playset of Nissa, Who Shakes the World for late-game sustainability. Here below is a decklist that finished in 2nd place and piloted by Brad Nelson.
