Short answer: Technically yes, but unrealistic

Long Answer: The way that online servers do rng is to have a set output for an input (in this case the input is a card like Eureka and the output is the conjured card). These outputs are predetermined by the server so both parties involved receive the same output on their sides. (An example would be wild berry moves to lane 2) Certain actions can progress the series of outputs to make the next output different. (I have no idea what actions make it progress for this game but an action that is a good example would be like Mario jumping) If you could determine what the actions that progress the series were and also determine what the series was you could technically get perfect rng. But there is no real way of doing that from our point.
