I wouldn't use even the most fine tuned fbtnb offense in type 1 2 player because scattered and Foreign wives are basically in every competitive deck. Scattered cripples the deck and at
least forces you to attack in small chains that are easier to beat. Foreign wives makes now makes set up difficult because with pentecost, firstfruits, mustering for war, and ishmaiah are not liabilities when you want to make rescues. To run an effective fbtn deck you really need to set up your chain quickly AND keep it going.
This deck (honestly) isn't even close to an ideal fbtn banding build. If you would like to look at one, try
Martin Miller's build that won nationals a couple years ago. He didn't even play that style at last years nationals. If you have questions about how it works let me know.
Generally though his fast defense is what you are looking for in a deck like this. Pharisees are the best for that because they are the fastest while at the same time have a lot of decent blocks for such a light defense. This year I think you are on the right track for defense. I doubt a light defense will cut it as it will not be able to sustain the blocks it needs to overcome Foreign Wives and Scattered. On the other hand if you run a middle to heavy defense your offense won't set up as fast and will therefore walk into scattered more often. At least you may be able to hold them off for a while if your defense is larger. The one thing going for you is that fbtnb is really good against the meta defense. Personally if I played it in a tournament today I would use a warriors Gabriel/Hidden Treasure tech to get rid of scattered. In summary, I would try something else for tournament play but if you decide to check out Martin's (TH3Un4giveable) so you can streamline it more and add some techs.
