Lore2 Level 4 monsters
If this card was Xyz Summoned by using at least 1 Dragon-Type or Wyrm-Type monster as an Xyz Material, this card cannot be destroyed by battle. If this card was Xyz Summoned by using only Dragon-Type or Wyrm-Type monsters as Xyz Materials, this card is unaffected by Trap effects. Once per turn: You can banish 1 Dragon-Type or Wyrm-Type monster from your Graveyard; this card gains ATK equal to half the banished monster's ATK, until the End Phase. Once per turn, during either player's turn, if any player's monster battles: You can detach 1 Xyz Material from this card; negate that attack, then if the battling monster is a LIGHT or DARK monster, this card gains ATK equal to the Level/Rank/Quality/Wavelength of the attacking moster x200.
