DeckCheck (because of the code and AI model it uses) will occasionally produce responses that are incorrect or misleading.

This is known as "hallucinating" information, and it’s a result of the current limitations of AI models. The most common example of this is when DeckCheck recommends a card that is outside of your commander's color identity. Another example is when it recommends a card that doesn't exist. Some of this hallucinating can be stopped with updates, and some of it cannot.

Please do not rely on DeckCheck as a source of truth. Carefully scrutinize any high-stakes recommendations given by DeckCheck.
