Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
prediction: gouki hijacks krack's account and uses it to almost win 6-0 until darklucario summons the power of the dark(ie) to come back from a 1-6 deficit to win 3-0 (he used revives).
Both Krack and DarkLucario are very lucky, but you can't get to the finals of Smogon Tour without at least having some luck on your side. I don't really know who to root for, but I have a feeling that DarkLucario is gonna take it all ;_;
