How it works
Activate Selvala by paying and tapping it, adding at least 6.
Activate Quicksilver Wall by paying 4, returning it to your hand from the battlefield.
Cast Quicksilver Wall by paying 2.
Chakram Retriever triggers, untapping Selvala.
Repeat.
If you control a creature with power 9 or greater, this combo nets infinite colored mana, and you may untap any creature you control.
This intricate loop hinges on Selvala, Heart of the Wilds, whose ability to tap for massive amounts of mana is fueled by having a sufficiently large creature on your board. To keep the engine running, Quicksilver Wall bounces itself back to your hand for four mana, allowing you to recast it and trigger Chakram Retriever's passive ability. Each time you cast the wall, Chakram Retriever untaps Selvala so you can tap her again for a net profit of mana.
