STANDARD DECK GOES TO TIMELESS!! Budget Mono Red Aggro for MTG Arena

Deposed king of Standard Bo1, Mono Red with Leyline of Resonance, goes up against the Timeless format. Includes deck list, deck discussion, and gameplay footage. I don't have a pun or joke for today's deck, so I will go with an old favorite...Disney's Frozen isn't my favorite movie, but it IS my favorite conspiracy theory...
