Here is some of my advice for picking up a tank this next campaign even if you are not a unicum or dark blue player.
You need the right tanks and some experience in them. If you put yourself in a position to apply for clans and let them know you have these tanks available with 3+skill crews you have a great shot at getting one. You have 2 weeks to get them and I am sure you with some Blueprints and other XP you can get close.
There are some really good Mid tier clans out there that successfully get tanks for their teammates campaign after campaign.
