Hi @quantumodo,
Thank you for your bug report regarding cards “12024” and “45030a”, and for sharing your save file.
However, we don’t believe this is a bug. The text of “45030a” states:
You may play the top card of your deck as if it were in your hand.
We interpret this to mean that the top card of your deck can only be treated as if it were in your hand for the purpose of playing it. It may not qualify as a legal target for “12024”, which requires a card that is actually in your hand.
We aren’t entirely certain this interpretation is correct. If you find any FAQs that clarify this, please let us know.
Thank you!
