Amareth, the Lustrous
Legendary Creature — Dragon

Whenever another permanent you control enters, look at the top card of your library. If it shares a card type with that permanent, you may reveal that card and put it into your hand.
"Come closer, dear, and let me see that bauble. I've got a match for it somewhere..."

Card types that can appear on permanents and cards in a library include artifact, creature, enchantment, land, planeswalker. Instant and sorcery are card types, but they can't appear on permanents. Legendary, basic, and snow are supertypes, not card types; Dragon and Pirate are subtypes, not card types.
