Spirit Reaper vs Gorz the Emissary of Darkness

When reaper attacks directly,and the opponent have gorz or tragoedia in hand both effect go on chain so spirit reaper is a MANDATORY effect and has to be placed on chain link 1. Gorz is an OPTIONAL effect and if desired will be on chain link 2. Gorz will come out, SS the token, then spirit reaper will randomly discard the card from the opponent's hand.

Same goes for X-Saber Airbellum and for X-Saber Urbellum.
