This is my nature deck that got me 19/25 in the last weekend ranked starting Mythic. More losses was from deception and then i had to switch to nature, so i would have gotten more than 19 wins if i'd play only nature. Its a budget divine order and wellcome and core cards only, no genesis, not even trial! If u cant afford Finnian i would suggest you to go with 1 extra low-hanging fruit because it seems very similar. Same kind of decks with genesis cards like underbrush ofc will be stronger but it can go well in Mythic. I think i dont have to explain u how to play this deck, its simple. Fight for the board, finish him with the help of sudden bloom, suddenly...
!HINT
Against (vs) Magic its always better to play with the Animal Bond spell in order to make him waste his spells on these tragic creatures. Be ware when u play ur important creatures!
