You can add any item in already started game :
1) shift + tilda (~) (gray area for typing text will appear)
2) type `item item_name` (go to game folder/sessions/items.txt and find right name for item you want to `cheat` into your inventory. Expl orcs ear you type `item uho_orka` , or for Fools`s cap type `item joker_hat`)
3) Enter , open your inventory and item should appear in it.
There is no guarantee that you`ll ever find full set in game (couple are almost always there but not all), so try playing with cards that you`r dealt. Have fun
