This deck needs SSA.
I didn't really want to test this but I found time and tested it with physical cards and I felt that the SSA version was the best out of the 2 strategies I managed to test. Pure Aquaactress lacks protection and that's where SSA comes in. I don't have it in-game, so I can't share the list at the moment, but it's basically maxed Aquaactress + 3 Whale, 2 of each Aquarium and 2 SSA...+2-3 whatever u want.
Then you lost the support of the spell cards to make beatsticks though. This deck loses against anyone willing to stall as is. SSA gets over that but then it's easier to swarm beaters against the deck.
