FROM SHADOWERA WIKI:
Homunculus is a tribe of allies in Shadow Era. They were introduced in Dark Prophecies, with further support in Shattered Fates. This type of ally are made up of creatures which have been artificially created by their specific faction (they have members on both the Human and Shadow sides). They seem to have a wide range of effects, some involving the graveyard, attachments, and attack/health increasing.
Lore: The Homunculus alignment is tied together by the idea of created allies, usually with some elemental (fire, ice, electrical) theme or being created from other allies. Then growing and augmenting them.
As I look over the tribe in general and read the wiki about what the alignment is, I can’t help but think of the Frankenstein monster. Essentially the tribe is using “pieces” from your hand and “parts” from graveyards to grow your allies. So far the shadow side of the tribe revolves around discarding from the hand and exiling from any graveyards to manipulate the board and receives one or more bonuses from doing so. The human side appears to be a wisp (no real synergy), electric theme and a combination of temporary and actual growth. The neutral side appear to be all over the place but provide some additional choices for both the human/shadow builds. Homunculus decks are generally ally heavy and very reliant on items and attachments specifically, with a splash of other abilities here and there. Homunculus having access to all the different types of combat damage really makes me appreciate the Frankenstein approach of the tribe much more.
