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.
When Quicksilver Wall enters the battlefield, Intruder Alarm triggers, untapping all creatures.
Repeat.
If you control a creature with power 9 or greater, this combo nets infinite colored mana.
This clever loop transforms the humble Quicksilver Wall into an engine for infinite colored mana by exploiting the continuous untap trigger of Intruder Alarm. As the Wall repeatedly enters the battlefield, Intruder Alarm untaps Selvala, Heart of the Wilds, whose activated ability we tap to harvest a massive surge of mana fueled by having the greatest power among our creatures. We then funnel a portion of that generated mana back into the {4} activation cost to bounce the Wall to our hand, allowing us to recast and repeat the cycle indefinitely.
