Hey!
I'm so glad you reached out, I left you a message on the thank you thread on Reddit but I'm glad you got me here. I'm hoping to get some playtime with the deck soon! I'm really excited to play this style of deck as it's not something I've really ever played even though I'm a HUGE fan of all things Red. When I first picked up the deck and went through the cards I couldn't decide on the commander but after having more time with it and thinking I would definitely agree that
Niv-Mizzet Parun is the way to go. Until you said it I didn't even notice all the cards were gold! I love the gold theme and I have a perfect shiny gold sleeve I'm going to put the commander in. Thanks so much for taking the time to build this for me, I will report back as soon as I have the chance to play some games with it!
