dude i still cant trigger the card even though opponents activated a spell card...
and a question, "by paying their Life Points" whose LP? how much LP?
...How are you at all confused by this? It can only negate the activation of a Spell that has a LP cost, like Abyssal Designator or Autonomous Action Unit.
after that, my next turn, i attack again and he activated his michizure or something i cant remmebr the name but my cashback is not triggered again..
but on the text it's said that the card's negating the activation of spell/trap, or monster. well, he 'activated' the trap so why cant i activated my cashback?
