Things I would try and include is Thorn Collection (x2 - obviously if you can't get them, I'd try and include another Natures Wrath) Remove Petrichor add Treefolks Blessing (not needed with those portal mages) Remove Brambles add combined effort (for more nora gen, and nice card mid game) Remove Escape Magic Add Protection (just a better rune all together, I've noticed EM is far more situational than protection) (possibly) drop Dreambox and add another Horn of Order Otherwise, good bg. I love the tortun theme. If you can eventually get some Tortun captains, they are extremely quick in FF KF..
you should create your bg with this website, i never used it, but it seems to be greate, others bg posts have it a lot: http://poxbase.com/#!/home Like this wizard BG posted some time ago http://poxbase.com/#!/deck/coxC4fC5ACjbc8bCw1cincklcgTco7c9lcoQs7s1as7WS2ts6gr3nr2YrUr25R3we2weM
I have a whole guide for tortuns that you can check in my signature or in the split faction forums, it includes FF KF and every other possible split too. Right now my FF KF tortun battlegroup looks like this: http://www.poxbase.com/#!/deck/c2c5FcinChYCyPCo7CyOcyDcyAcyGCyFcimS7s2@S1aS2ts6gr3nr2YrUE2w But there are plenty of variations.
