Gilder Bairn + Iceberg + Hankyu

Gilder Bairn

Iceberg

Hankyu

How it works

1. Activate Hankyu by tapping Gilder Bairn, producing its effect.
2. Activate Gilder Bairn by paying 2G/U and untapping it, doubling each counter on Iceberg.
3. Activate Iceberg as many times as necessary by removing counters from it, adding at least three mana.
4. Repeat from step 2.
5. Once you have infinite counters on Iceberg, you may instead double the counters on any other permanents.
