Well... then you still need to beat horde, but you should try scorched earth. Also if you will be lucky, timur will die. Still as rebels won't spawn on their cores, you will need to help them. Anyway you should build two 15k stacks - one on asian side and one in europe, and start doing mission - while beating timurids. Better don't make peace with them - as this will only strenghten them. When they start to break - make colony is eresrum, and when it will become your province - demand them to concede defeat - if they will have less prestige, they will be weaker - but do it only if they will start to break to the rebels. If they don't, then just continue colonizing, province by province, and use mountains to defend agains any stacks they send - aslo don't assault, and if your morale will be low, withdraw to turkey, so they don't destroy your forces. While you fight timurids, also you should do your missions - it might be hard, at the beggining, but otherwise you won't grow in power. Also it is quite possible that you will need to fight golden horde - in their case, use scorched earth, and when they will lose their army, or their armies fight elsewhere - colonize their provinces up to bessarabia - when you got bessarabia and budjak as your provinces - make peace with GH - if you are at peace with timurids and don't have any wars - and release moldavia. You need moldavia as a buffer state, so that you won't just fight them all the time. Also to do the trick you need another vassal, so vassalize wallachia. If you will be lucky - you will no longer border horde, which might bind your hands to expand in other places.
