Goofball, if you won all your matches, you would be guaranteed to move on. You would have the head to head tie breaker against anyone that could tie with you at 4-3.
No, he wouldn't. To break tiebreakers like this, I am taking the wins of the opponents defeated and comparing. If Flygon is beaten twice, that'd leave Delta, goof, and Ironbullet left. Delta would have 6 from limitless, 3 from LN, 1 from KD, 3 from _Flygon_, which is 13. Ironbullet would have 3 from EnZ0, 3 from LN, 4 from Delta, 1 from KD, which is 11. Goof would have 4 from Delta, 4 from Iron bullet, 1 from KD, and 3 from Flygon which is 12.
Now if Flygon beats Limitless, Flygon would have 3 from enz0, 3 from LN, 4 from Ironbullet, and 5 from Limitless, giving him 15, and giving both Delta and Goof only 13. However, since there are only 3 tied people, round robin could also be used, but only once. If no winner is determined after one round robin, we'll take the wins from the opponents system to avoid being here all day.
So tl;dr version:
Goofball will advance if, these steps happen:
1. Flygon defeats Limitless.
2. Goofball wins 4 in a row
3. Goofball defeats Delta2777
