Oni Pact-Taker

Deathtouch
At the beginning of your upkeep, you may sacrifice a Goblin or token artifact you control. If you do, put a pact counter on Oni Pact-Taker, then search your library for a
card with mana value less than or equal to
the number of counters on Oni Pact-Taker,
put into your hand, then shuffle.
