If you ever have a fancy for mid-big lawt, buy it. EX: Zug is meh in the file and replaceable, but normal zug is a great endgame. What i should really say is this file is great for people new to lawtia. The only real selling points are francis and the zugs, which are preference based. If you don't have vet swordswoman, death knight, zombie lord, merc death, night wing, then buy it. Oh yeah XXXX. Hes good against rushes, sometimes. I don't really like him that much, EVEN with regus engineer support.
In short, mid/big lawt= fun but very hard to use in current meta.
