AETHERFORGE GUARDIAN

Whenever another nontoken artifact enters the battlefield under your control, put a charge counter on Aetherforge. Remove three charge counters: Create a colorless Equipment artifact token named Aether Dagger with “Equipped creature has haste and first strike” and “Equip legendary creature {0}.” Attach it to a legendary creature you control. Activate only as a sorcery and only once each turn. Remove four charge counters: Put two -1 / -1 counters on target creature an opponent controls. Remove five charge counters: Look at the top three cards of your library. Put one into your hand, one into your graveyard, and the rest on the bottom of your library.
