[How to chose "Banish" for Armor]

Just to update, this wasn't a bug.

 

 

I had not played the App version of the game before, and had never actually seen a card Banishment.  After playing more, I realized the option displays on the right-side of the card when applicable.

 

I think the original problem was me overlooking the damage was coming from a Bunyip, and therefore not reducible.  

 

 

Thanks for everyone who answered.

[How to chose "Banish" for Armor]

Sorry if the question seems silly, but I can't seem to figure out how to Banish an Armor card for it's "reduce all damage to zero" ability.

 

The only option next to the card (Leather Armor) is "Discard", and the damage is regular combat damage.

 

Proficient allows Bury instead of Banish ... but how do I Banish?

 

Thanks.
