Registeel LA Once during your turn, you may discard 2 cards from your hand. Then... Junk arm Discard 2 cards from your hand. Search your discard... Why are the ruleing different on these 2 cards so registell can be used with no effect and junk arm can´t? They both make you discard 2 cards and then do a effect. Like the rules are like now you should be able to use Porygon Z from triumophant dimension transfer with no trainers in the discard pile. Please correct me if i´m wrong about porygon z. Why should this be allowed to search the discard pile for trainer then junk arm isn´t.
