FFG's web site is great at letting us know how many of which color sleeves to purchase for every product... except the Conversion Kit - which, ironically, is loaded with cards, isn't it?

Does anyone know which color and how many?

it has 50 or so monster cards and 3 or 4 mini cards. the rest is hero sheets.

There's exactly 50 monster cards and 3 familiar cards (same size as shop items). Check the photo for which sleeves you need, I dont put my hero sheets in sleeves so don't know what colour those need (and if they make them or not at the size)
