Excavation Rigging

Whenever a Scout creature enters the battlefield
under your control, it explores. (Reveal the top
card of your library. Put that card into your hand if
it's a land. Otherwise, put a +1/+1 counter on that creature, then put the card back or put it into your graveyard.)
Whenever a card is put into your graveyard from
your library, you may tap target artifact or
creature.
