How do I use the cards like "poison" effectively in this game, without people noticing?
GAME - HANDH
A good example of poison use is to place them discretely when doing other things. For example you could put it under the soap dispenser when you go to the washroom, or you could drop one in a bowl of popcorn you set on the table for guests to eat, etc. The key is timing and areas large enough to cover the card until it's interacted with.
