[Adventure] Unsupported card when "Enable non-legal cards" is unchecked.

[Eradev]

Describe the bug
Merfolk Lord had an unsupported card in its deck.

Maybe the current implementation of not loading the cards should be revised?

I think the original creator of that deck intentionally added those funny cards, seems easy to update the deck but there should be an internal evaluator so it will be replaced with something usable by the AI.
