To resolve Nezumi Informant's ability in a multiplayer game, the next opponent in turn order (or, if it's an opponent's turn, the opponent whose turn it is) chooses a card in hand and sets it aside without revealing it

In this case, you can cycle a card with basic landcycling like Ash Barrens to search for a basic land of any type and put it into your hand
one quick glance and you know exactly which Pokmon you still need to hunt down to finish the family
