I have been working on Czechoslovakia expansion for a while and i have gathered some examples of to show of new strategy called Sabotage: "Each time a unit attacks, it costs one more kredits to operate." With nation spawnable PARTISANS and kredit exhausting tactics you should be able to hold down an enemy while you build up your combo to deliver deadly punch to their HQ.

Must say the sabotage mechanic might bring back the throp play style with America. Also I think spirit of nation should at least be a limited card cause it provides some pretty strong control orders with Prague and Slovak uprisings
