First of all, I thank you for your answer, It has everything I could ask for.
Now, I'm totally new at WH, so yes, I'm just starting an army and I want to play both AoS and standard and almost any possible combination I can.
You are welcome!
Well, if you are just beginning to collect Seraphon, I think the Starbeast Constellation is the fastest way to have a very consistent army ready to be played.
I mean, if you buy this bundle, you can be sure you won't need to buy anything else for at least one or two years! XD
Ok, you might want to integrate some models (Slann or Salamanders, for example) in the future, but undoubtedly you will never feel the "I can't play because I don't have the models" sensation XD
So these are my advices:
- if you have the possibility (money, time, space) get this bundle. It's all a Lizardmen/Seraphon lover could ever desire;
- try to figure out which models you will really play and which are redundant: I suggest you to sell these ones, in order to substitute them with Kroak, Chameleons or what you prefer;
- have fun with this amazing collection and enjoy all the envy the other Lizzies players will feel towards you!!! XD
CAUTION!
You must take into account these thing too, before proceeding with this buy.
- These models will require you a lot of time (playing and/or painting them). If you are not sure you can dedicate it to them, probably you could buy a smaller amount of units, and expand it gradually.
- You sure you really like Lizzies? I mean, my twin bought an army of Tomb Kings long time ago, but after a few months he realised Skaven were his true love [rats surely took control of his mind

] ... This MUSTN'T happen to you, cause of the cost of this bundle.
- Be sure you like Warhammer and Age of Sigmar: you don't want an entire army staying closed in a box cause you have found the game was boring for you
Now, I think I've finished to write walls of text: from now on I'll try to write shorter posts, for the joy of everyone!
P.S. If you ever realise you don't need one of those Stegs, or 45 Temple Guards are more than you use, or so on, remember of that poor
@Freddy25 guy that so kindly suggested you all those things in the Lustria Online forum! XD (I'm joking, but I hope what I said helps you in some way).
P.P.S. Thanks for the Dino King explanation!
