Thanks Maciek Kotula. Changling will surely find a place but I don't think that I will put out Will of Tzeentch in near future. I like it that much because I play a lot of handcards out and it can often ruin the opponents game. Especially if you look to Troll Vomit, Master Rune of Spite or this kind of cards that opponents like to keep on hand for the right moment like damage cancels, attacker remover and of course Verena setup cards. I had games where 1st or 2nd turn Will of Tzeentch decided the game. Depends how good your starting hand is and the Q-zone should at least give you 2 cards. In midgame just make sure the opponent has no units/support in his Qzone then play it. If the opponent doesn't draw something to establish his quest again he will loose the game because usually the chaos board is better positioned especially when Kairos is out. I also think it's a great tournament card because it's good and also nobody expects it. So you will surely catch your opponent off guard and ruining his strategy when 1st playing it.

I really like Unleashing the Spell but I think it's not optimal with Kairos because you don't want to loose your precious developments. Otherwise it would be a good finisher but not that reliable. A responded My Life for the Hold can really mess with that plan. Tomorrow I will get Eclipse and then I will know better how it plays out.

As said in forum I don't need to speed it up. Of course it depends on playstyle and local meta. I found it recently that the old version doesn't stand a chance against quick orcs, so I decided for some corruption tactics. Good old Seduced by Darkness is a good counter for RiP attacks and Warpstone Experiments which is now in nearly every destruction deck. Also switched back to Warpstone Excavation. There isn't the threat of visit anymore and I also felt myself low on supports (9x previously). It also helps against Troll Vomit to get not completely reseted.
