You can play Blue eyes + arkana.
Dragon Spirit of white is less expensive than cosmic cyclone, you get two copies of it with just 1000 gems. Banishing traps with it is quite easy.
SSA decks are often slow to set up their combo, so the best way to beat them is put pressure on them from the beginning, by OTK'ing them, forcing them to waste resources just to stay alive, or preventing them from having 2 WATER monsters on the field.
If they have already set up the SSA combination, force them to banish the Whale by threatening their Umi with a back row removal card, or by threatening their Whale for example with Canadia + Econ, and then attacking directly.
You can destroy Umi when SSA is active with cards like 'Double Cyclone', 'Twister' and ' Unending Nightmare', you chain them to the banishing effect of SSA / at the moment that they flip up SSA
So: SSA player banishes a WATER monster/flips SSA face up --> you chain Unending Nightmare to Umi. If you activate Double Cyclone as chain link 1, and they banish a WATER monster, you cannot destroy it.
I main an SSA deck and one of the most fustrating things for me is when I have my Fisherman or Citadel Whale out and they are the only monster on the field, I would have to banish them when my SSA gets targeted which leaves me completely vulnerable to attacks.
