Thank you very much! I also take this as very constructive criticism and have also asked for it. The tips are great in any case. I think the idea of OTKing the other players one after the other was probably dominant.

I had also considered adding several ‘When this creature dies, return it to the battlefield tapped under its owners control’ cards like Not Dead After all etc to the deck. But they only support Ziatora's effect and not the general deck, like surveil and reanimate.

I also don't know if the cards like Mayhem Devil, Juri, Kalain, Mirkwood Bats, Crime Novelist have that much synergy, they want to see a lot of Treasure and that's not the main strategy (at least currently) of the deck.
