A Vengeful Puppetmaster

Playing a new game of EUIV, playing as Poland. My Empire is glorious, and I have several empires' fate in my hands (most notably Muscovy, who if I break my alliance with Muscovy they will crumble, and if I keep my alliance with them they will grow back). For the most part, my glory was pinned on one accidental event, in which I was able to defeat Muscovy in a war early in the game, and again a couple decades later. Now, my glory stretches from Russia Proper to Germany and even France, as I carry a personal union with Austria.

But only a couple years before this map takes place (~1630's), I fought and was defeated by the Emperor, King of Franconia and Bavaria and his Holy Roman Cronies, and my defeat to them has been taken quite hard (all I lost was a total of two provinces and a vassal, but I felt like they had destroyed my entire empire). I plan for vengeance.

Now if you excuse me, I have to start planning for my next Winter Invasion of Russia, because I can get away with that apparently
