Cursed foundries are a bad choice on hansels. Decide on the attack stats u want and use t5 buildings instead of t4. Reason is the less # of attack buildings a hansel has, the more the plunder curve stays even. Example let's say u want 1 mil 300,000 attack roughly, u could have 3 CoE's or more like one Colony. The one colony is better. My build has 3 colonies, makes it easy to hit all lvls of ebs. The # of attack buildings is just personal preference for me though.
On my build, I have 1 colony, 4 hatcheries, and the rest SoS. Probably not the best for ebs but I like the attack for when I do estocs sometimes.
