2+ Effect Monsters
If another monster is Special Summoned to a zone a Link Monster points to, while this monster is on the field: Discard up to 2 random cards (min. 1), then your opponent discards the same number of cards. If this card is Extra Linked: You can make your opponent discard 2 cards (or their entire hand, if less than 2), then, if they have no cards in their hand as a result, inflict 3000 damage to them.
