I control Dark Horus. During my opponent's main phase, he discards Destiny Hero - Malicious to pay for Destiny Draw. After the chain ends, I want to trigger Dark Horus to special summon Kycoo the Ghost Destroyer to hose my opponent's potential Malicious play. He, however, wants to remove Malicious to get another from his deck. Does this situation work like summoning Exiled Force while King Tiger Wanghu is in play, in which the King Tiger triggers immediately denying the opponent the ability activate his ignition effect? Or, because Dark Horus is optional, can my opponent activate Malicious and force me to chain with Dark Horus if I want to use it at all?
