Please don't play simian spirit guid or other mana accelerators in burn. Our deck is already fast enough , all we need is consistency. Ask yourself this question : how many times i see just two lands in the entire game ? Now imagine if one of those lands was a spirit guide. This would mean that you can cast only a 2 mana spell during the game and then play very slowly with just one land.

You need stable mana to cast your spells. You need at least 2 lands to finish your opponents in a reasonable time. You can't gamble playing spirit guides hoping to accelerate your gameplan.... this lead just to inconsistency.
