How competitive?

Hi guys,

So I've got the option of trading my Jund deck into a mostly FOILED version of Bant Company + most of E-Tron, and the Bant list has a lot of the pieces to play this. Firstly, do you guys think this is a good trade? I come out with $100 in in my favour.

How competitive is this deck? Should I feel bad trading away my modern Jund for this deck? Would really be interested to hear some insights.

Thanks, fellow Knights!
