first of all, I wanted to make special mention of race and invented the "Spartans"
I had thought the same ability to a race, but he overtook me, and the name of the race, bound like a glove
Now my ideas:
*** gaea's servants***
humanoid warriors defenders jungles and vast forests, say they were wooden skin becomes when receiving blows or cuts
(when receive the second attack boost, always defend like you have an army of 8)
COST: 2.400 shards or 60 golds
***guerrillas ***
Their military training is limited, but are experts in creating ambushes
(when attacking with a 2 army, as an army will always be 3)
cost: 2.000 shards or 50 golds
***mercenaries ***
When they can not make the surprise attack, take the time to prepare a plan
(+X% ATTACK, +Y% DEFENCE// "X" equals the number of opponents that lies behind the starting position in the game, "Y" equals the number of opponents that lie ahead of the position)
cost:2.200 shards or 55 golds
***Clone***
these creatures sent to mingle aliens among us, we do not know if it's your first attempt to integrate, or else a test to begin the invasion
(Purchase the bonus and/or racial abilities at random , of one of the opponents)
cost: 1.800 shards or 45 golds, available free with premium account
