Basalt Monolith + Animating Faerie // Bring to Life + Biomancer's Familiar

Basalt Monolith

Animating Faerie // Bring to Life

Biomancer's Familiar

How it works

1. Activate Basalt Monolith's first ability by tapping it, adding CCC.
2. Cast Bring to Life by paying 2, making Basalt Monolith a 0/0 artifact creature and putting four +1/+1 counters on it.
3. Activate Basalt Monolith's last ability by paying 1, untapping it.
4. Activate Basalt Monolith's first ability by tapping it, adding CCC.
5. Repeat from step 3.

This clever loop hinges on turning a familiar mana rock into a creature using the "Bring to Life" half of Animating Faerie // Bring to Life, which crucially reduces Basalt Monolith's untap activation cost down from three mana. Because Biomancer's Familiar sits on your board as a creature, its static ability steps in to discount that untap cost by {2}, dropping the price of untapping Basalt Monolith to just {1} mana. Since tapping the Monolith generates three colorless mana, you net two colorless mana with every single iteration of tapping and untapping, safely producing infinite colorless mana for your spells and abilities.
