Personally, it always seems super reasonable to me when I lose to a Mono-Red Aggro deck, especially in high-powered Cubes
Not only do topping Decks suffer, weaker Decks like Heraldics (at best they get a 2000 beatstick who is a RotA when he dies) and Scraps (can peak at 2500, but usually will hit 1900 instead, and the Synchro Monsters are one of the biggest parts of making the Deck work)
