Niventine, Grand Artificer

Whenever an Artificer with converted mana cost
X enters the battlefield under your control,
choose up to one:
•Look at the top X cards of your library. You
may reveal an artifact card from among them and
put it into your hand. Put the rest on bottom in
any order.
•Put an artifact card with converted mana cost X
or less from your hand onto the battlefield.
