+ I Bottomless Trap Hole. I just prefer 3 because it can protect you from SO much like Dark Armed Dragon and Synchro's, Chaos Sorcerer, Sky Scourges. Speaking of Sky Scourges, you should add in one Enrise, since you have Sangan in.
1- Mobius. You already have 2 in there, having 2 Mobius and 2 Zaborg should be enough. xP
