I take 8, including all of the ones I need to – Rostov, Yaroslavl which have forts and were developed, their capital of Galich, the copper mines of Viatka, etc
I spend around 350 ADM to core them
Orthodox:
Yelets – South of my holdings in the southeast beneath Oka, Tula and Pronsk, this Mishar culture group of people have 7 development, Steppes, livestock, and a church here
Viatka – The last major prize Muscovy had. Copper mines west of Perm the nation, north of us at Kazan, Glazov and Ishkar. 15 dev, Muscovite, woods, and south of our new holding in Ust-Vym
Ust-Vym – Total throw-in. Just captured by Muscovy from Perm about a few months before we took it. Forest, fur, church, 3 dev. East of Novgorod. Uralic people here.
Rostov – The former capital of the nation, 11 dev, grasslands, Muscovite, farm estate, workshop, church all here, grain farmers. Connects our holdings in Yaroslavl to Yuripev
Yaroslavl – Former capital. Grassland, livestock, 16 dev, workshop, level 2 castle, Muscovite. Connects Rostov to Kostroma
Kostroma – Cloth is made here in the woods, 9 dev, Muscovite, in the center of the area that connects Yaroslavl, Galich and Vologda
Galich – Former capital of Muscovy. Salt, woods, 13 dev. North of NN, south of Kostroma

These are all of the remaining good places in Muscovy. The next war likely ends them.
There you are!
