Card Rules: Rulings powered by The Netrep API. This is a Trigger Effect This effect activates in the Damage Step , before a face-down monster is flipped face-up. (Therefore this effect will not activate if a face-down 'Neo-Spacian Grand Mole' is attacked. Also if 'Neo-Spacian Grand Mole' attacks a face-down Flip Effect Monster you can return both monsters to the owners' hands without activating the Flip Effect.) This effect does not target. [Re: Doomcaliber Knight] When multiple Effect Monster effects activate simultaneously 'Doomcaliber Knight's' effect is chained after determining the order of the Effect Monster effects (see the Advanced Rulings FAQ 'Simultaneous Effects) and will negate the Effect Monster's effect that was placed last on the Chain.Example 1: Player A Tributes her 'Sangan' and 'Witch of the Black Forest' to Tribute Summon 'Dark Magician'. 'Sangan's' effect is Chain Link 1 and 'Witch of the Black Forest's' effect is Chain Link 2. The effect of Player B's 'Doomcaliber Knight' is chained and it will negate 'Witch of the Black Forest's' effect.Example 2: Player A and Player B have 'Goldd Wu-Lord of Dark World' in their hand and Player A controls 'Doomcaliber Knight'. Player A activates 'Card Destruction'. When both copies of 'Goldd Wu-Lord of Dark World' are discarded their effects start a Chain. Player A is the turn player so his 'Goldd Wu-Lord of Dark World' is Chain Link 1 and Player B's is Chain Link 2. 'Doomcaliber Knight's' effect is chained and it will negate Player B's 'Goldd Wu-Lord of Dark World'.Example 3: Player A's 'Giant Rat' is destroyed in battle and sent to the Graveyard while she has 'Green Baboon Defender of the Forest' in her hand and 'Doomcaliber Knight' is face-up on the field. Player A can activate 'Giant Rat' and/or 'Green Baboon Defender of the Forest's' effect. If she activates both effects she chooses the order the effects are placed onto the Chain and 'Doomcaliber Knight' will negate the effect that is placed highest on the Chain. If 'Green Baboon Defender of the Forest' is Chain Link 1 and 'Giant Rat' is Chain Link 2 'Doomcaliber Knight' will negate 'Giant Rat'.Example 4: If 'Sangan' is Tributed to Tribute Summon 'Raiza the Storm Monarch' while 'Doomcaliber Knight' is face-up on the field 'Sangan's' effect is Chain Link 1 and 'Raiza the Storm Monarch's' effect is Chain Link 2. 'Doomcaliber Knight's' effect is chained negating 'Raiza the Storm Monarch's' effect and destroying it.Example 5: Player A's 'Sasuke Samurai #4' attacks Player B's 'Neo-Spacian Grand Mole' while 'Doomcaliber Knight' is face-up on the field. 'Sasuke Samurai #4's' effect is Chain Link 1 and 'Neo-Spacian Grand Mole' is Chain Link 2. 'Doomcaliber Knight's' effect is chained and it will negate and destroy 'Neo-Spacian Grand Mole'.
