The Weakest Link (Red)

When this hits a hero, look at their hand and choose a card without base

. If you do, they discard it and you draw a card.

Base is the printed value on a card. (Located at the bottom right corner of a card.)
You must choose a card that does not have a printed property. Cards that have 0 printed or cards that have asterisks (*) for their value are considered to have a printed value. If you do not choose a card, the hero hit by The Weakest Link does not discard any cards and you do not draw a card.
The effect does not trigger if you hit anything other than a hero (i.e. an ally).
