Urza, Lord High Artificer + Pili-Pala + Training Grounds

Urza, Lord High Artificer

Pili-Pala

Training Grounds

How it works

1. Activate Urza's first ability by tapping Pili-Pala, adding .
2. Activate Pili-Pala by paying 1 and untapping it, adding one mana of any color.
3. Repeat.
4. Once you have infinite mana, you may use it to activate Urza's ability.

This elegant transmutation of mana relies on the cost-reduction of Training Grounds to make Pili-Pala's untap ability a profitable venture, turning its self-contained untap into a net-positive engine. With the activation cost reduced to just one mana, you can repeatedly tap the scarecrow for blue mana using Urza, Lord High Artificer's second ability, then pay that exact mana right back into Pili-Pala to untap it and generate any color of your choosing. Once this infinite loop yields boundless colored mana of every stripe, you can funnel it directly into Urza's massive five-mana activated ability to continuously exile and play your entire library without paying mana costs.
