So turns out.....

....coming up with ideas for nine powerful but hopefully not over powerful cards was pretty easy.

Now if they are actually balanced or if there game breaking - that will have to wait till a play test to find out

The cards are....

Declare peace with one person for one turn - this is basically adding back the recently removed 'Invite your neighbor' card - which always seemed a little over powered.
End a conflict and retreat attackers bits without resolving. 
Remove enemy big man - and gain 1 attack or defense. Not sure if this should be +1 or +2 a 3 point swing is good but not that much better then a standard card, well a 4 point swing seem pretty damn good.
Cancel card just played - and take into your hand.  Improved version of totally taboo
Get a card out of the discard pile or search through the deck for it - a classic gaming power that's not in the game.  While not powerful it does mean you can pretty much get the card you need.
Steal 3 cards from an opponent - which is going to ruin somebody's day.
Score an extra one for each head you flip - does not allow you to flip heads.  Could yield about an extra 4/5 VPs if played right - but you do still need a way of flipping them. 
Put your big man into this fight from off the board.  Seems like just a 2 point swing - which it is - but provide they live - saves you the cost of bringing them on next turn which is also plus 1 person.
Take an extra man, an extra card, and an extra giant stone head. Not a game changer - but a nice boost.

So questions to be answered - who gets these bonus cards and when do they get them?

I think that on turn 2 and turn 3 - everybody but the last two players in the turn gets a card (so in a 3 player game the 1st player gets on, in a 4 player game players 1 and 2 get them, and in a 5 player game players 1 to 3 get them).  The first player draws as many cards are going to be given out - keeps 1 - and pass the remaining cards to the next player - who keeps one.  So 3 players - draw 1 get that.  5 players - draw three - keep 1 and pass 2 on.  Not sure about the user interface for this to make sure it happens and does not get forgotten.....

So onto the next bit - RongaRonga cards - creating opportunities to gain VP's and hurt people who are doing well.  These have to be changed because
