Card Rules: Rulings powered by The Netrep API. You may Summon 'Thunder Nyan Nyan' even if you have non-LIGHT monsters on the field , but she will be destroyed. You can have face-down non-LIGHT monsters on your side of the field 'Thunder Nyan Nyan' will not be destroyed by her own effect but if one of these monsters is flipped face-up she will be destroyed. When you take control of an opponent's non-LIGHT monster and you have 'Thunder Nyan Nyan' on the field she will be destroyed. If your opponent takes control of your 'Thunder Nyan Nyan' and he / she controls a non-LIGHT monster 'Thunder Nyan Nyan' will be destroyed. You can Special Summon 'Thunder Nyan Nyan' with the effect of 'Cyber Jar' but if you Summon another non-LIGHT monster face-up she will be destroyed. 'Thunder Nyan Nyan' can be destroyed by her own effect between steps in a chain. For example the opponent targets your 'Thunder Nyan Nyan' with 'Snatch Steal'. You chain 'Call of the Haunted' to Special Summon 'Dark Magician' from your Graveyard a DARK monster. The chain resolves as follows: 'Call of the Haunted' resolves 'Thunder Nyan Nyan' is destroyed because there is a DARK monster on the field 'Snatch Steal''s effect disappears because the target is no longer on the field. If you have a face-up 'Thunder Nyan Nyan' and your Set 'Penguin Soldier' is attacked when it is flipped face-up 'Thunder Nyan Nyan' will be destroyed before it can be targeted by the effect of 'Penguin Soldier'. [Re: My Body as a Shield] 'My Body as a Shield' can only be used against effects that will destroy monsters at that time. So you cannot use 'My Body as a Shield' when 'Tribe-Infecting Virus' is summoned you can only use it in response to the activation of 'Tribe-Infecting Virus''s effect at which point the effect of 'Tribe-Infecting Virus' is negated and 'Tribe-Infecting Virus' is destroyed. Also you cannot use 'My Body as a Shield' against cards whose effects will not destroy a monster right away so you cannot use 'My Body as a Shield' against 'Jigen Bakudan' 'Ekibyo Drakmord' 'Magical Hats' 'Steel Scorpion' 'Toon Monsters' 'Thunder Nyan Nyan' 'Gradius' Option' 'Summoner of Illusions' 'Limiter Removal' 'Call of the Haunted' 'Premature Burial' or 'Autonomous Action Unit'. [Re: Prime Material Dragon] 'Prime Material Dragon' can only be used against effects that will destroy monsters at that time. For example you cannot use 'Prime Material Dragon's' effect when 'Dark Armed Dragon' is Special Summoned you can only use it in response to the activation of 'Dark Armed Dragon's' effect when it targets a monster. Also you cannot use 'Prime Material Dragon's' effect against cards whose effects will not destroy a monster right away so you cannot use 'Prime Material Dragon' against 'Jigen Bakudan' or 'Arutonomous Action Unit'.
