Filigree Artisan

When this creature enters, look at the top five cards
of your library. You may reveal an artifact card with mana value 2 or less from among them and put it into your hand. Put the rest on the bottom of your library in any order.

Whenever a nontoken artifact with mana value 2 or less enters under your control, you may
pay {1}. If you do, draw a card.
