No frills for me, thank you. I play really slow at times, and burn gives me a chance to simplify life while enjoying the game.
My only other choice would probably have been weenie, since it's sometimes hard to figure out if a Sligh-ish deck is burn or weenie or whatever.
On the difference between basic deck concept and deck archetype: While I don't know that I've seen this distinction in terms of wording before, I would suppose that a basic deck concept would be an item like those in the poll, while a deck archetype has a more specific focus (what color, what combo, etc.). The concept weenie becomes Stompy, WW, Sligh, etc. Counter becomes Nether-Go, Forbidian, etc. However, I actually would probably prefer a more general definition of archetype than a lot of people.
