I have mixed feelings about this card. I love it because I love Ents, and the artwork is fantastic. But honestly, Wellinghall Preserver is a better use for 3 resources, which are precious when you play Lore. I like that he is only really worth it in mid to end game because of his ability--that's thematic--but even then, Wellinghall Preserver can heal and has a consistent 3 . So Leaflock is really only worth it if you have 4 or more damaged Ents, and even then you get 1 in exchange for the ability to heal near mid to end game, otherwise he is an inferior Wellinghall Preserver. I think they could have balanced this by giving him maybe 1 more hp, or made the max buff +5 instead of +4.
