- When I use the Supporter "Fisherman," can I put less than 4 Basic Energy cards from my discard pile into my hand?
- If you have 4 or more Basic Energy cards in the discard pile you must put exactly 4 of them into your hand. But if there are less than 4 Basic Energy cards in the discard pile, you must take them all.
