I use SPlat against FG. It's just so much stronger than my old RoL/Hope.
I just skip Scorpio, Incarnate, Ferox, Fire Queen and Elidnis. I've won against all the others (miracle can be hard, but doable most of the time).
In platinium, I'm having better results with my own deck. As you said, somehow, platinium decks adapted themselves to the combo. SoSe is good to stay flexible and hard to counter.
