LongPike: English localisation;

I play the sapper first, target the 4 dogs, but don't get a shot to target the boss afterwards.

If I play an ally card first and then the sapper, I also have to kill the ally because the boss stays immune.

Hickory: Sapper >> Barghest, Barghest, Barghest, Bargetst >> End Turn

Alchemist >> Charge Onager >> End Turn
Epidemic >> Onager >> Beast, Beast, Beast >> End Turn
Alchemist >> Charge Sapper >> End Turn

Victory!
