Tolbjorn, the Forge-Priest

Vigilance, first strike
When Tolbjorn enters the battlefield, you may
exile an artifact card from your graveyard. If you
do, search your library for an artifact card with converted mana cost less than the exiled card,
and put it onto the battlefield tapped. Shuffle
your library.
Other creatures you control get +1/+0 for each equipment you control.
