Cloudian Ra now works well after the rebalance.
You still need to be careful of Navigation's graveyard effect though. You cannot respond to the graveyard effect with Divine Punishment, likely because you can't destroy what's already in the Graveyard.
Forgot to mention, I also run 1x Diamond Dust Cyclone for draw power.
Zeradias is also usable for deck thinning by using its effect even though you already have Sanc up, so that you can get the needed cards faster and win before your opponent decks out first.
Luck maybe, but he never use Thousand Knives on me early in the duel.
Also, I have a feeling Navigation is bugged. When I farmed Bakura, I can respond to his Sangan's effect that activates in the Graveyard, using Divine Punishment. Which means I should be able to respond to Navigation using Divine Punishment.....but that's not what's happening in the game.
Navigations grave yard effect is not considered a card activation. You are just using an effect. Spell/trap are only considered to be activated when flipped face up if set or played face up from hand.
