You already have Hermitic Herbalist but lack support.
Prioritize Shared Roots or Lost Days.
Ramp, answers and something worth ramping into. Do not count restricted Lesson mana as unrestricted mana. Cheap defense matters more than a third expensive payoff.
You have Hermitic Herbalist and can use the interaction.
Consider Lost Days for the next useful piece.
Herbalist supplies two mana toward Lost Days because it is a Lesson. Removing a threat and making a Clue helps recover the turn spent ramping.
The support is missing
Keep broadly useful creatures and answers; if the special reward is missing, build a complete deck before chasing it.
