[OSFE] Something interesting about this game is how each ending type encourages building a different kind of deck

For mercy runs, you just build a normal deck capable of beating bosses and shit, it's a fairly standard finale

For neutral runs, you want things that deal damage over large areas, since each of the eight tiles taken up by the Gate can be hit separately

Fire cards play extremely well here

Firewall is like 720 free damage

And for no mercy runs, you want longevity. The true endboss has a shitload of health and defense so you want things that will serve you well in a long, drawn-out encounter

Selicy neutral clear

OKAY

I have gotten pacifist clears with EVERY CHARACTER

now it's time for some neutrality

extremely funny: the "whenever you hit with a kunai, gain a kunai" artifact

when fighting the Gate

because it's so big that it's impossible to miss

so you're just mashing both spell buttons as fast as you can and never running out
