Nice writeup . I got to play against a similar build with my Yisan . I didn ' t expect the lock thought it would be infectproliferate shenanigans , but I was pleasantly surprised by the raw power . While the strenghts are obvious , I ' ll go over some weaknesses that I noticed 1 It ' s weak againt dork strategies . At least weaker than Derevi , because Derevi compliments his plan with extra turns , and can stay en par with huge mana swings of Selvala and other elfballs . Once I stuck few little elves very basic landdrop dork , goes around most of the deck ' s locks , I crawled out of the lock easily while my opponent was digging for wipes . 2 It has weak interaction with passive triggers like Meren or Joira . 3 It struggles if the commander is not around . Song of the Dryads shut down the whole thing for a long time in my games . 23 removals , and the decks is running at 50 % power .
