At the beginning of your upkeep, if you have three or fewer cards in hand, this artifact deals 1 damage to target opponent or planeswalker.
You target one opposing player each time the ability triggers.
It checks the number of cards in your hand at the beginning of upkeep and does not trigger at all if you have more than three. It checks again on resolution and does not deal damage unless you still have 3 or fewer cards.
