Discard a 2nd Junk Arm when using Junk Arm

[SLOW DECK]

Discard 2 cards from your hand. Search your discard pile for a Trainer card, show it to your opponent, and put it into your hand. you can't choose Junk Arm with the effect of this card.

If I have a trainer in my discard pile. I play a Junk Arm, can I choose another Junk Arm in my hand as one of my cards to be discarded?

Thanks

Sure, you can discard a Junk Arm. You just can't get one back.
