Legendary Creature - Angel
Flying
You and Humans you control have hexproof.
2, Exile a card from your graveyard: put a 1/1 white Human Soldier creature token onto the battlefield.
4/5
It's aegis (who is much cheaper) + kira (also cheaper, and wider effect) with a good body and a token generator. The cost is high for a Humans deck, maybe too high, but the effects are awesome. If you are playing Noble hierarch and or deathrite shaman is easier to ramp into it, while it could be unacceptable in mana denial strategies.
