"free" tavern tickets... arena and duels?

greetings everyone. 

will i get a "free" ticket for both modes, or is this just arena only?

thanks.

Noone knows for sure about the Duels, Sinti wants to try it first.

I'll try it out as well. I have  a few tickets to spare and it makes sense to get one just as with Arena.

I started an arena and duels run, and just now I got a refund for my arena run, but my duels run is still going.
