The Sibsig Ceremony + Junk Diver + The Immortal Sun + Workshop Assistant

The Sibsig Ceremony

Junk Diver

The Immortal Sun

Workshop Assistant

How it works

1. Cast Junk Diver by paying 0.
2. When Junk Diver enters the battlefield, The Sibsig Ceremony triggers, destroying Junk Diver and creating a 2/2 Zombie Druid creature token.
3. When Junk Diver dies, it triggers, returning Workshop Assistant from your graveyard to your hand.
4. Cast Workshop Assistant by paying 0.
5. When Workshop Assistant enters the battlefield, The Sibsig Ceremony triggers, destroying Workshop Assistant and creating a 2/2 Zombie Druid creature token.
6. When Workshop Assistant dies, it triggers, returning Junk Diver from your graveyard to your hand.
7. Repeat.

This brilliant loop relies on a clever reduction in mana costs provided by The Sibsig Ceremony and The Immortal Sun, which together slash a combined {3} off creature spells and reduce the cost of our artifact creatures down to zero. With the entrance fee eliminated, you can endlessly cast either Junk Diver or Workshop Assistant, only for The Sibsig Ceremony to immediately strike them down and replace them with a 2/2 Zombie Druid token. As each artifact creature hits the graveyard, its death trigger fires off to pluck the *other* automaton right back out of the graveyard and into your hand.
