just faster mill to draw better things as you know how some of these monsters are weak enough to be run over by anything, you are better off to either special summon them or put a few into the graveyard and pick them up with salvage or ocean later XD;
But the only thing that Ocean could pick up is Stratos and other Ocean, the former unaffected by Skreech and the latter kind of useless in this deck (if there's something on the field that the first one can't stop, the second one isn't going to help you any).
...In all honesty, Stratos and Ocean look to be there just for the sake of being there with Reinforcement or maybe Salvage. They're not really doing anything for you besides just sitting in the deck, so I'd have to suggest dropping them (and a single RotA with them since the only remaining target is Rose) for something that can actually help with the theme you have going, like the Sangan that's somehow missing. Between all of the bouncing and potential Morphing Jar recycling you have going on here, Protector of the Sanctuary might be worth a look in this deck for the hand-depletion factor and extra walling. If you want to focus specifically on dedicated bouncing, then the overlooked Dark Cat with White Tail could work for the sake of doing both of Penguin Soldier's potential tricks at once if you flip it during your turn, although it'll admittedly be trouble if it gets attacked. And, with Moon and Eclipse flipping everything facedown, you should probably be running Nobleman, or Shield Crash at the very least.
So, the fix would be something like...
-3 Elemental Hero Ocean
-1 Elemental Hero Stratos
-1 Reinforcement of the Army
+1 Sangan
+2 Nobleman of Crossout
+2 Dark Cat with White Tail OR +1 & +1 Protector of the Sanctuary
As long as we're talking about just playing this deck for fun, I would also like to randomly toss the name Degenerate Circuit into the mix.
EDIT: I can't believe I missed this before: Junk Synchron & Warrior, anyone? Even before any of the above changes, you have four Level 2 monsters in there, three of which can be dragged out and recycled as necessary. It would only make sense to play off of this with a big beater, right? It'll at least give those Penguins something else to do once they've bounced the opponent's field as well as more reason for discarding them for Abyss Soldier's effect.
