I thought than I can edit my post but no...
SECOND GAME :
Ironjawz player :
1x Maw Crusha
2x Warchanter
6x Gruntas
3x Gruntas
20x Orruks Ardboys
5x Orruk brutes
Scenario was : "The better part of valour"
I was very afraid of this scenario, with my only 3x5 Liberators... But I think I was lucky to have an Ironjawz army as opponent. my plan was to place a liberator unit in a corner of the table alone with the auxiliary objective "bait", destroyed as soon as possible this objectif and move them to the objectif in the middle . In the opposite corner an other liberator unit with my 2 stardrake and wizards to keep this objectif all the game like and win 8 points. The last liberator unit stayed in the sky to have a constant threat for my opponent.
It was the plan... But my opponent played Ironjawz and played like an Ironjawz too. So he rushed all my army and he didn't care all objectifs. Lucky for me, because with no MW, my army is too tanky for him. The Maw crusha charge was brave, but he did nothing on my stardrake...
So same as the first battle, in the end of the round 2 he had lost too much to continue the game and decided to give up. Major victory for me, it was unexpected on this scenario.
THIRD GAME :
Tzeentch player :
Lord of change
blue scribes
changecaster
changeling
Magister
3x10 Pink horrors
2x Flamers
Scenario : "Battle for the pass"
Honestly, I don't know how I could have won against him, the player was Goul a very good AoS player. So I decided to focus on the auxiliary objectifs to have a good place for the tournament. I started the game with a defensive positioning and I started to kill all his leaders. He placed his pink horrors on objectif very fast and for me it was a nightmare to move them after... At the end of tird round I couldn't get back to the score. But I succed my auxiliary objectifs and I killed all his leaders.
Maybe I could have try to focus pink horrors after discussion with my opponent, but I'm not sure to have enough damage for these.
CONCLUSION :
Very happy for my first tournament. I think I was little bit lucky with my opponents, but my list was very strong and very regular. Each battle I do soo much damage than my opponents can do nothing to stop it, but if he take too much advantage on objectifs I can do nothing to change the result...
Thanks, I think I will insist to don't take the Castelant. My feeling is than this list is too much tanky and only MW are a threat. During my games I lost :
1st game : 2 liberators
2nd game : 7 liberators
3rd game : 5 liberators and the Prime
Hope you'll appreciate my feedback
