Interesting..I use a different but similar strategy.
1. Use Colodi to give all puppets Focus.
2. Use Brutal to give support condition for every Puppet.
3. Vasilisa walks/picks up Stitched Together and bring it to either a scheme marker place or to negate the opposing players sceme runner.
4. Use Vasilisas (0) Action to get the stiched to either gamble you life (with Focus) or place a scheme marker.
If a scheme marker is placed I get a free 4" move with Vasilisa.
5.When I activate The Stiched I get Fast and either attack target with mass Gamble or use Focus to get of 1-2 focused attacks or place a scheme marker (with again a free Vasilisa move).
Used this way Vasilisa + Stiched can move around the board every turn, supporting where is needed. I am also a fan of using two henchmen, so I combine Vasilisa with the Widow Weaver for some additional move.
The downside about this is that you have to keep an eye on when you need Vasilisa and her "Strum the threads".
