Gilder Bairn + Paradise Mantle + Training Grounds

Gilder Bairn

Paradise Mantle

Training Grounds

How it works

1. Activate Gilder Bairn by tapping it, adding G/U.
2. Activate Gilder Bairn by paying G/U and untapping it, doubling each counter on target permanent.
3. Repeat.

This clever engine turns Gilder Bairn into an exponential growth machine by turning its untap cost into a self-sustaining loop. Paradise Mantle grants the Bairn the ability to tap for mana, paying the hybrid cost required to activate its counter-doubling ability. Meanwhile, Training Grounds slashes that activation cost down to just a single mana of any color, ensuring the loop can perpetually fund itself while continuously doubling counters on any permanent of your choice.
