Hi, there are some issues with your list that can be tabled turn 3 to be honest.
Orks can be "competitive" only spamming
MSU. 'ard boyz, meganobz in a BW, large squads of lootas, gretchin and koptas are not optimized choices, and the morkanaut is among orks worst units. Even with the best efforts and the most competitive orks lists available you still won't win any tournament that involves supercheesy lists.
Ok zhadsnark, bikes, boyz in trukks, koptas, lootas, grots and meganobz. But they can perform in a list which would be something like that, considering what you listed:
Zhadsnark (150)
Painboy, bike (75)
6 warbikes, nob, p.klaw (143)
2x10 boyz, nob,
bp,
pk, trukk, ram (270)
10 gretchin (35)
3 meganobz, killsaws,
bp, trukk, ram (170)
3x1 deffkopta (90) I hope bringing three solo koptas doesn't mean for you to spam them
2x5 lootas (140)
Which are approx 1100 points. If you don't want to spam bikes (at least 6 other bikes could be handy though) add other boyz and tankbustas in trukks, always min expendable units. Also a third unit of 5 lootas can be helpful.
