Quote from squirrelmastersbiotch »what if helm of the host is equipped to legion warboss? would the new legion warboss token ability trigger before going into the declare attackers part of the combat phase?
No. The Warboss needs to already exist when the Beginning of Combat Step begins for its ability to trigger. The token-copy is created when Helm's ability resolves, and at this moment it is already past the "beginning of combat" point.
