Hahahaha what a joke

I remembered 1 EGD build in AP/CW and tried it with my ghosts : 1 stack of cursed ghosts, and 1 stack of an other unit:
step 1 - battle start kick ghosts in enemy line,
step 2 -on other unit cast invisibility
step 3 - repeat step 2, until every other unit is dead
step 4 - cast heal on ghosts until they return under control
This was possible because i found rage eater (5 mana/5rage every turn). I killed kraken on 11 lvl, with 50 cursed ghosts battle finished with something over 1200
