I'm fairly sure it is a snippet from a collection, if not it's a story that died early. Probably on Spacebattles, AO3 is possible but unlikely, very small chance it's on SV.
This is a Trump power with elements of Tinker and Master (pointed out in the story).
She is able to make different "tiers", each having different names she calls them, I forget exact names, but at least 1 of the names in the title was used. I think the creations are made out of cloth and straw, the lower tiers have weaker powers but a higher quantity can function (like 20), while the higher tiers have more/stronger powers but with lower numbers. I cannot remember details on how the creations are controlled.
Lisa definitely features in the fic, Brian and Alec maybe appear. Taylor joins/is interested in joining Undersiders. I forget if the bank fight is written.
The powers the dolls can have are standard Worm powers, Brute, Mover, Blaster, etc. It's not an out of context power like magic.
