Chieftain doesn`t trigger with Vamana

[Robdrop]

Hello

Just happened to me two times that Chieftain didn't trigger when my 3/3 Vamana died.
Maybe with other reincarnate units too?!?

This is working as intended. In Hand of the Gods, the Reincarnate keyword refers to units being sent to the Hand instead of the Graveyard, so this does not count as a unit's death.
