Core Set 2020 Promos

In a Two-Headed Giant game, Glint-Horn Buccaneer’s triggered ability causes the opposing team to be dealt 1 damage twice.

The middle ability of Glint-Horn Buccaneer is a triggered ability, not an activated ability. It doesn’t allow you to discard a card whenever you want; rather, you need some other way of discarding a card, such as by activating its last ability.
