Hidden Nationality Unit can capture workers

But the Capturing Animal -> Great Zoo is awesome (+2

for all cities, and additional

from animal cages in cities)
And the Hero Assassin (forgot the name

) is crazy - 9 Attack + Mirror, requires only poison

AND he starts with Hidden Nationality.
AND it`s very easy to capture animals in early time

p though may hurt the economy for unit upkeep), as its Scout has +1 Attack (with +50% Bonnus, its 4.5 vs Animal

)
Tech Route is Necessary Start Economy Techs (get Animal Husbandry in time) -> Festival (for the Grand Manageric) -> Poison -> Military Str (for blitz, I didn`t got the Axe) -> Animal Handle -> Deception
Once the Hero Assassin`s on field, I threw him into my poor neighbor`s bolder and hack & slash his units (for EXP

). Then he`s capable to take down cities all by himself and some assassins (World Spell to hide the assassins ^^, Killed all guard and left the city unguarded). Then the war declared with rangers flooding in
The Hero Assassin gots 746 EXP before he`s got killed in a 99.3% odd battle
It feels good to see the AI units flooded to my hero and converted into EXP when I placed my hero on a Hill with Forest and a Zealot (for heal, Nationality not hidden

I`ve no religion that time)
Only problem for me is the Arcane Trait is hard to exploit - Svartalfar has only "Support Magic Nodes" - Shadow, Nature and Mind. All of them are not good for build an offensive mage force

(Just not worth for Soccery, as Gibbon can get lv2 shadow + lv2 Nature very easy and can move in enemy terrain without hidden nationality or open bolder).
