The strategy is clear, if you go first make calamities, make the union carrier + simorgh link combo, and you have infinite negation and your opponent cannot attack to destroy thunderbird, so you won, didn't you? In this game there are cards like droplet and dark ruler no more so you don't win but it is a strong combo to go first. But ehi it's Fluffal so if you go 2nd you're happy so you can go first and you can go second as well.
For who was asking the going first combo work with Foolish Burial Goods + patchwork + a fluffal between dog, dolphin and sheep (this is just an example, you have a lot of hands that make you do this combo)
There is a edopro’s replay with the combo:

The Side can be revisited, I am "poor" and I only have these options at the moment.
P.S. I'm sorry if my english isn't perfect but i'm not a native language, but i tried my best.
Edit: here you can download the combo video if you don't have edopro:
