The setup is: bears - 1 wolf - 1 wolf - 1 wolf - 1 wolf - 1 goblin - Rukh - wolves.
In the first round, the defender from the bottom left stack is removed; the wolves from the blessing stack knock him out; the Rukh wait; the bears attack the top left stack without removing the defender; the single wolves run to the left; the goblin moves to the bottom horizontal. After the move, the Nagashir attacks, and the Rukh attack the top left stack.
In the second round, the Rukh are blessed and finished off; the wolves wait; the goblin removes the defender; another stack is eliminated with wolves, with the intention of having the wolves then hide in the top left corner. The bears wait (they will need to hide or distract the Nagashir later).
The Nagashir advances; here, it is important to separate the two stacks, which is why the wolves need to hide correctly – so that one stack can reach them in 2 turns, and the other in 3. Then, the two stacks are eliminated one after another, with the single wolves removing the defenders (the bears cannot do this because they are weak).
Losses: 3 wolves and 1 goblin, 98.3%. I am considering replacing one of the wolves with a goblin; in theory, at least one of the eliminations should be possible from a waiting position.
