"Newcomer-2011. Winter"

well actually a nest of birds when building bears in castle is 3+7+7+9=26 birds
it's unclear where 15 wood elves came from in the native army :)
in three such a creg will have all his eater burned for sure, only thunders and bears will remain) and also vague doubts gnaw at me about bringing bears into castle as a standard, you might build them, but how on day 121 to tempo-buy and transport all folders to the treasure zone is quite an interesting question :)

generally to take a Dragon Utopia you need to fulfill 2 simple conditions
-having a strike stack with 700+ damage
-having an eater that can survive at least 3 rounds

obviously mass shield and stone skin make the task much easier, there is a subtle point here, to cast spells before the greens and reds move it is highly desirable to have something with speed 11+ (even a single one!)
also an interesting observation:
- if on the 1st move our stack of angels (or say monks) hits greens or reds, then both will peck exactly it in the same round
- casting shield or stone skin on a unit sharply increases the chance it won't be touched
- dragons terribly love to peck nagas, hydras, crushers, horses, and dendroids (conclusions depend on each specific situation :) )
and also the classic way to take a Dragon Utopia with 7 singles of anything and a hero with SP 10+ and summon elementals — when 1 green remains, if there is no ex recursor we simply run away and finish off the unfortunate dragon with a scout hero :)

Disgrace damn!!!
