Forum:Just a few small Q's

1. If a person actives 'trap jammer' and the opponent counters it with 'seven tools of the bandit', does the person who actived the trap jammer still have to discard a card?

2. If a person actives a trap card and a the opponent counters it with the 'mystical space typhoon', does the effect of the trap card still go on?

3. if the opponent actives 'mystical space typhoon' on a set trap card like for example 'jar of greed', could you still active the targeted trap card (jar of greed I mean)?

Thanks for your time.
