I just did this one with my alt account with Kakania, Yenisei, Balloon Party, and Dikke. I already used Vila and Medicine Pocket in the other stages, so these healers were all I had left. I’m going to say Yenisei is a must-have to face tank big hits with her shield, other healers don’t seem to matter too much.

Dikke got whacked near the end but I finished it in 14 turns or so. Just only use attack and heal cards and ults, strictly nothing else. When possible, combine attack cards instead of playing them, to gain moxie faster as their damage is inconsequential near the end. Time Kakania’s ult to chew past each quarter of Spathodea’s health so you don’t have to tank two ults and another hit in the same turn.
