If you play Random Receiver, and reveal a Supporter on the first card you turn over--such that there are no "other cards"--do you shuffle your deck? Thanks!
Random Receiver (Trainer--Item)
Reveal cards from the top of your deck until you reveal a Supporter card. Put it into your hand. Shuffle the other cards back into your deck.
