I'm just new to WH40k playing,but there's some nice stuff I'd seen:
1.In a kill-team game I saw 6 DA Marines wiped out all 15-men IG by losing only 5 men in 3 turns.
2.In a Necrons vs DA,8 Cron Warriors get shot down but then 7 come back to life.
3.In the same game,8 Scarab Swarm were wiped out when they attack a T squad in CC,for only killed 1 T.
Now here's mine in a 2v2 game last Saturday:Tau(me) and Ultramarines vs Blood Anges and CSM(Black Legion).We limit our forces for 1 HQ,1 Elites,2 Troops and 1 Fast Attack.
1.The CSM player called his CSM "cannon-fodder" but he killed off about 11 FW in my team.
2.You better think about that is my dice get cursed for a Crisis team and Shas'O with all Missile+Plasma can only kill about 11 CSM in 2 teams in 4 turns.......
3.Same about my dice,the CSM used my dice for his CSM Armour saves(3+) rolls and failed almost all.Afterwards,he and his ally didn't use my dice anymore.When they picked up my dice and looked at them,they'll put them down and used their own dice instead,and said that my dice are "cursed" if used by enemy.
4.Ultra DN vs Daemon Prince.
The DN shot its Twin-Las at the Prince but failed to wound.
Prince went into CC (OMG it has about 11 attacks) but can't penetrate DN's armour.
DN stroke back,no wound.
And in the next turn the Prince blew the DN up without suffering a single wound.
5. 9 CSM/PSM with Chaos Wind Deep Striked at my back(but very near to the table edge) and killed off my 3 Crisis Suits.And then it took me and my ally an entire 2 turns to wipe them out,finally by Ultras in CC.It pissed me off very much,since I'll have to put my 'O and a FW team shooting at the back while the CSM advanced.
6.The game didn't end properly,since the CSM player had been took away by his mom and gf,most probably.
Enjoy.

Horus was weak.Horus was a fool.
He had the whole galaxy within his grasp and he let it slip away.
LET THE GALAXY BURN!!
FORCES OF TAU AND CHAOS,BOW TO ME!!
