…For example: Spiders Eat Insects is the Goal in play. I had the Insects in play AND Poison (Camouflaged). It was my boyfriends turn and he played Spiders, whereupon I instantly revealed the poison card…
A: When we came up with those two cards, we never considered that someone might want to Camouflage their Poison! But it should be no problem to have played it the way you did. You are absolutely allowed to reveal your Poison just after he’d played Spiders to indicate that his Spiders would not be able to successfully eat your Insects, thereby preventing his win at that time.
We imagine it as a predator snapping up prey, not knowing it was poisonous, and then realizing it tastes like nasty poison, and spitting it out! Bleah! Like a bird eating a Monarch butterfly for the first time and puking. Yeah, that one Monarch died, but that one Bird didn’t succeed in eating it, either, and the overall effect is that Birds avoid eating Monarch butterflies. (The example is a bit weird with Spiders, but you get the picture.)
