Pia's Revolution is pretty sick, right? Your opponent can choose to take 3 damage or return a dead artifact back to your hand. No good options for them! Magnificent. How can we abuse this?
The current Standard meta gives us a good deal of powerful artifacts to work with that are capable of sacrificing themselves. Bomat Courier, Hope of Ghirapur, Implement of Combustion, and Walking Ballista are all given a playset.
3 damage if they choose to take your artifacts is pretty bad for them. Let's make it worse. We can hurt them coming and going with 4 Reckless Fireweaver. Delightful.
If they don't want to play our game, and are happy with dealing with our artifact recursion, great. Now we just need a suite of burn spells. We are Nalaars, we bring artifacts and fire. 4 Shock, 3 Incendiary Flow, 4 Burn from Within, and 3 Release the Gremlins for some straight up removal that we can sacrifice our own artifacts with in a pinch and get a field of blockers for our efforts.
Lastly, 2 Chandra, Torch of Defiance. She gives us a lot of options when she comes in, and her ultimately is fairly attainable in many match-ups.
20 Mountains comprise the mana base. Cheap, easy, consistent. Our mana curve runs low and our temperature runs hot!
