Quentin, Artful Investigator

When Quentin, Artful Investigator attacks or
blocks, Investigate. (Create a colorless Clue artifact
token with "{2}, Sacrifice this artifact: Draw a card.")

At the beginning of your upkeep, if there are 7
or more cards in your hand, search your library
for an artifact card with total converted mana
cost equal to or less than Quentin, Artful Investigator's toughness and put it onto the battlefield under your control, then shuffle your library.
