In my opinion Queen Mycelia is the best defensive card to replace Sprit Of The Forest. All of her 4 abilities are supportive and she is good with almost all game modes. She gives 2+ shield,heals the friendly back-line monsters, reduces the armor of all enemy monsters and her amplify ability increases magic reflect,thorn,return fire damage by +1 . I think out of all defense cards in earth team she is the perfect one.
