I'm just wondering if anyone knows at least one of his decks structure?

I'm very curious, could learn something about deckbuilding from how he does it or something, and just witness a world-championship-winning deck.

Here you go :

Cool, thanks. Does he uses it all the time?

I highly doubt it. Most long-time players change their decks pretty regularly, I'd be surprised if he'd used it more than a few times in the last year.

There's always new ideas to try out, new cards coming out, etc…

I saw his photo with two Mother's Hands on the table. Interesting.

Yep, those came out together too.

Pay 4 for Mother's Hand, which is an overpay so you can refresh the domain and use it again.

Pay 4 for another Mother's Hand, which is an overpay so you can refresh the domain and use it again.

I don't remember what the 3rd card out of that domain was though…
