United in Stormwind Cards List & Guide
This is a super weird one and I can't think of any other card with the same wording.
If this were the intended interaction, the language usually used would be 'After you play an Overload card...'. However, this is written 'After you play a card with Overload'.
We have plenty of examples of the text for this kind of expected interaction other card types with:N'Zoth, the Corruptor
Corrupt the Waters
I would argue that because of previous wording precedents Guidance is a card with overload, but it is not an overload card, and that therefore the current interaction is not the intended one.
