Thick Hide Hunter (Yellow)

Thick Tide Hunter triggers when it resolves on the stack and becomes an attacking card, or when it is added as a defending card against an attack (i.e. declared as a defending card in the defend step or added via an effect.). When the triggered effect resolves, you must discard a random card from your hand.

Discard a random card is not an additional cost. You can still attack/defend with this card if you don’t have any cards in your hand.
