Thanks for the input, the online deckbuilder seems solid albeit a bit confusing for me.

So I guess a Mage Wars version of those template deckbuilders like ringsdb.com , arkhamdb.com, netrunnerdb.com or dtdb.co is currently not in the works?

Can a Mod please split this thread?
Half of the discussion has nothing to do with the initial topic.

Thanks guys for the fast answers.

My cardpool is: 1x core set, 2x spell tome 1, 3x spell time 2 and all available expansions 1x.

I understand that the meta is still quite small and that there is lesser amount of serious testing and analysis like in MTG. I browsed the complete spellbook list but the problem for me is that a lot of the builds aren't up to date (regarding the current card pool). I can understand that this game is more about the player than the content of his spellbook and I'm not looking for the best build around, I'm looking for 4 equally strong builds.
So, instead of asking about the best books, I probably should ask, what do you guys think are the 4 strongest mages (if you have to rate them) and on what strategy/core cards you should focus with them.
