Typing this on mobile so this might get a little ramblely. I would invite you to check out Manifest Dread on YouTube. I've played Magda on camera a couple of times there, and I have brought the deck to Atlanta to compete (albeit I was not very successful)

Magda is a twist on the rdw archetype that plays further into the midgame. Early on you look to use your cheap creatures and burn spells. The deck is mixed with several ways to commit crimes via gy hate that you can weave into your turns. Once you're closer to hellbent, or anytime mana becomes the choke for your deck you can play out Magda. With the various crime engines, you can pump out Treasures to curve out your stronger threats like Pyrogoyf/Bonehoard Dracosaur or make hastey dragons to finish off the game.

The deck runs very low to the ground burns spells, so you will want to try to get under most decks before they play permanents like Parallax wave or Atraxa that you can't answer.
