Rules on the mana Drain are very clear you cannot just post a decklist this is going to get closed fast. next time maybe give card information and tell us from your toruanment Exp why some cards are main and sideboard and what matchups if any are you afriad of and what other people have been doing with Sligh for the current metagame.
I find it funny that you are trying to be all moderator-like but at the same time write this with terrible grammar and English.
anyway, check out this thread:
