Piru, the Volatile EDH Deck

I like the idea of having a deck where you use a legendary Elder Dragon as your commander. But, I knew that I wanted to build on a budget. I've edited the deck quite a bit over the last few years, mostly to make the deck under 100$, but partly just to swap for new cards.

I wanted to use one of the six Elder Dragons that is a 7/7 with a respective upkeep cost, and my favorite tri-color combination is Mardu, so I chose Piru. I also immediately knew what to do with Piru when I saw her.

The deck is about 80$ on TCGPlayer, according to the DeckStats calculator, and is based around using Piru's ability to board wipe creatures. The deck works better if your opponents play lots of nonlegendary creatures, but that isn't required to win how you're supposed to.
