Diligent Zookeeper (TLA)

Creature — Human Citizen Ally

Each non-Human creature you control gets +1/+1 for each of its creature types, to a maximum of 10.

Niche lord for creature-type-heavy strategies, but the bonus only applies to non-Humans and requires significant deck construction around multi-type creatures to justify the four-mana investment. Best in dedicated Changeling or Beast/Elf/Elemental decks where the payoff is consistent; otherwise, traditional lords like Elvish Archdruid offer more flexible value.
