Tx for this very very interesting post.

Stone skin is 3 mana.
3 trolls means 9 mana for 3 turns. So, it lasts 30 turns.
In 30 turns, my 3 trolls do 3 x 200 x 30 = 18000 damages (I do not count the move of the spider...). It lasts 18000 damages to kill the spider...

So, I am VERY interested in how the VERY easy way works, but instead of talking big with one single statement without explanation, may be you can go further in explanation ...?
Tx a lot...
