Board Game Arena

With the transporter card, are you able to pick and choose what to do with each card? Example of I have a hand of 4, can I trash 2 and discard 2 to still draw 4? Or do I have to do one the actions with the entire hand?

The Rules say:
Discard 2 cards from your hand to discard your next
Era card.

Or you mean Data Analyser?
With the Data Analyser you choose for each Card to discard or put back to yout deck.

Data Analyzer doesn't let you pick and choose, it's Destroy all or Discard all. Cyber Glasses does let you decide which cards to discard and which to return to deck.
