Exactly how slow are your games that you need to speed them up? I generally finish my games in less than an hour, so I think that any slowness may come from a lack of familiarity with the spellbook in question rather than the slowness of the game. Back in NC, we could get a new player to do point where they could finish games in an hour within a month, though that generally represented 10-20 games with the same spellbook.
Well my last game we didn't finish. We stopped after 2 hours or so (we did chit chat a lot, not a lot of thinking going on) I think there was about 2 hours left or so.
I played a Straywood BM book I've been playing for around 2 years now. Improved a lot
I played vs a book not unlike the book you just posted. A Priest that hardcasted GA´s and had a GA HA and a big Angel as well. Tuff to kill fast, even if I did a good job of ignoring the angels.
But I think most of our games in my meta, could go on longer than 90 min.
Wizard, Druid, any holy mage but even other mages with high defence and a lot of regen etc.
