In a 3 way brawl I think it's more likely Oceana and R'yleh view each other as imminent threats and they both try to get Atlantis to help them jump on each other. Not that it couldn't happen, but seems pretty shortsighted to both jump on Atlantis. In a 1 on 1 EA Oceana in the water is a beast, no doubt. I do think though that the deep atlanteans could be pretty nasty in this matchup with light research. Not having to worry about their MR, with a good strength + strength of giants + 2-3 attacks each + very low resources and fairly low gold cost I think you might be able to field enough to soak up Oceana's first strike, have enough attacks to overwhelm their (W blessed?) defense and hit hard enough to chip through their (E blessed?) protection. Spam some numbness on them and sprinkle in some earth meld...uphill struggle I'll give you, but I don't see a shutout.
