Its important to note that burn spells arent to be confused with a burn deck . The latter is an aggressive deck archetype that tends to play few creatures, instead aiming to reduce the opponents life total by targeting them with powerful burn spells
You can choose from three options: Amber and Amethyst, Emerald and Ruby, or Steel and Sapphire, or you can buy all three as a bundle
Another possibility is elf-ball, where you combine lots of elves that produce mana, Gaea's Cradle or Badgermole Cub, and a big finisher like Blightsteel Colossus to win
It will also stop that Dockside Extortionist from feeling so scary, especially since you can always pay one white mana and sacrifice Dauntless Dismantler to remove all of those pesky Treasure before they untap
Red decks need their removal to be able to go directly to the face, which is the one thing you cannot Terminate, and while being cheap is nice, the creatures you need Terminate for don't come out fast enough to reward you much for it being so cheap
