I don't know if this sounds right to you but might be related to what you are experiencing.
I expect more troll results when event starts. Whenever my opponents become active and improve their teams, the chances of getting trolled goes up. And this always happens during events as dead accounts get revived for collectibles.
I usually start off attacking then switch to normal then eventually defensive if i get that far. But not sure if you changing orders will help beat the troll as i think it is related to the engine giving our suddenly active opponents a chance.
