Goblin Bombardment + Naru Meha, Master Wizard + Extract from Darkness

Goblin Bombardment

Naru Meha, Master Wizard

Extract from Darkness

How it works

1. Cast Extract from Darkness by paying its mana cost
2. Holding priority, cast Naru Meha by paying its mana cost.
3. When Naru Meha enters, it triggers, targeting Extract from Darkness.
4. Holding priority, activate Goblin Bombardment by sacrificing Naru Meha.
5. Resolve the Naru Meha trigger, copying Extract from Darkness
6. Resolve the Extract from Darkness copy, causing each player to mill two cards and returning Naru Meha from your graveyard to the battlefield..
7. Repeat from step 3.

This clever loop relies on Naru Meha, Master Wizard entering the battlefield to copy Extract from Darkness, which mills your opponents and conveniently resurrects Naru Meha right back from the graveyard. Before that copy even resolves, you use Goblin Bombardment to cheerfully hurl Naru Meha at any target as a sacrifice, sending the Wizard back to the graveyard just in time to be targeted by the spell she just copied. As the loop repeats, Goblin Bombardment turns that endless cycle of sacrifices into lethal damage while Extract from Darkness continuously mills the library.
