Enchantress is overcome by Aztec riches sent across (5)
I believe the answer is:
circe
'enchantress' is the definition.
(figure of Greek myth)
'overcome by aztec riches sent across' is the wordplay.
'CIRCE' is hidden backwards within the letters.
However, I'm not sure how the hidden word is indicated.
'is' is the link.
Can you help me to learn more?
(Other definitions for circe that I've seen before include "she's into 20 [WITCHCRAFT]" , "Enchantress encountered by Odysseus" , "Enchantress visited by Odysseus" , "Odyssey sorceress" , "Greek sorceress who detained Odysseus on her island" .)
