kind annoying how insanely high your cards always are especially since this is a lose to get cg
Use the debug menu to set your HP to 1 and burn your good cards early into the struggle scenes. Yuria will escape once the sigil is filled with 3 "wins", but the sigil will lose 1 charge with each loss/tie
Use the stong cards (8-X) when the circle is dimmest to make room for more crap cards
Use the medium cards (3-7) when the circle is at 1 charge, as there is a chance the monster could actually win and effectively undo Yuria's previous win, but not risk losing
(You best want the sigil to be flipping between one and no charges)
Save the shit cards (1-2) for when the circle is at 2 charges and Yuria is about to escape to guarentee she stays and that the sigil loses a charge
