text: Joined Researchers's last ability will check as each end step starts to see if an opponent has more cards in hand than you. If none do, the ability won't trigger at all. It's not possible to discard cards or cause an opponent to draw cards during an end step in time to have the ability trigger. If it does trigger, the ability will check again as it tries to resolve. If no opponent has more cards in hand than you at that time, the ability won't resolve and none of its effects will happen.
