The text on the
Radioactive Potato says "Any time the goal changes, move this card in the counter-turn direction".
When the rule card
You Also Need a Baked Potato is in affect, you must have the radioactive potato in addition to the goal requirements to win.
Suppose a player has the
Radioactive potato creeper and the
Cookies keepers in front of them, and no other creepers or keepers. On their turn, they play the
Milk and Cookies goal. Do they win (since they have the goal requirements plus the potato) or do they not (since the potato passed to someone else)?
