Is Oni no Hatsu Suru an acceptable proxy for Hatsu Suru no Oni for ivory play despite the lack of "Soul of..." keyword? I figure it probably is but I am unable to find it anywhere in the Ivory rules. I hope I am not overlooking the obvious.
Hatsu Suru no Oni/Oni no Hatsu Suru
A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.
The Oracle of the Void includes this note:
MRP
Title changed to modern Oni name conventions.
So they're in fact the same card (they even share the Oracle entry) that was just MRP'ed
