Ghired, Mirror of the Wilds + Goblin Sharpshooter + Phyrexian Altar

Ghired, Mirror of the Wilds

Goblin Sharpshooter

Phyrexian Altar

How it works

1. Create a creature token.
2. Activate Goblin Sharpshooter by tapping it, creating a copy of the creature token.
3. Activate Phyrexian Altar by sacrificing a creature token, adding one mana of any color.
4. When the creature token dies, Goblin Sharpshooter triggers, untapping itself.
5. Repeat from step 2.

This ingenious loop turns a single initial creature token into an infinite engine of death and rebirth. Thanks to Ghired, Mirror of the Wilds, your nontoken creatures gain an activated ability that lets them tap to copy any token that entered the battlefield this turn, and since Ghired gives them haste, they are ready to work immediately. By sacrificing that newly created copy to Phyrexian Altar, you generate a colored mana and trigger Goblin Sharpshooter's untap ability as the creature dies. This constantly refreshed Sharpshooter can then tap to create *another* token using the Ghired-granted ability, ready to be fed back into the Altar for infinite sacrifices, leaves-the-battlefield triggers, enters-the-battlefield triggers, and colored mana.
