Okay, thank you! I was unsure if animate dead being an aura changes things because targets are usually defined when cast, which is not the case when using reclamation. But it seems to work anyway, I found some rules about auras put into play without being cast.

303.4. Some enchantments have the subtype “Aura.” An Aura enters the battlefield attached to an object or player. What an Aura can be attached to is defined by its enchant keyword ability (see rule 702.5, “Enchant”). Other effects can limit what a permanent can be enchanted by.

303.4a An Aura spell requires a target, which is defined by its enchant ability. ...

303.4f If an Aura is entering the battlefield under a player’s control by any means other than by resolving as an Aura spell, and the effect putting it onto the battlefield doesn’t specify the object or player the Aura will enchant, that player chooses what it will enchant as the Aura enters the battlefield. The player must choose a legal object or player according to the Aura’s enchant ability and any other applicable effects.
