The trinket does not work with the hero, they count double and it does not give the extra free tavern spell buy, also had to buy a tavern spell with coins while I had the passive for a free tavern spell active
“The first 2 Tavern spells you buy each turn are free”
The way this is worded, it clearly does not stack.
What were you expecting?
If 2 effects make the same specific card free, there’s no reason that also the next one will be free, if it’s what you expected
Which one of them ? Because it could be an independent issue
My ability said it was active, however I still had to pay to buy items in the shop
