while im not against fail to find as a concept since it would make things easier it could also break things since a lot of modern cards have not been designed with this in mind. think terminus sending a patron but not adding medius or anything with a positive cost
one thing I don’t get about yugioh is that you’re not allowed to “fail to find” a search target. like you’ll get a penalty if you play ROTA with no lvl 1-4 Warrior in deck. what’s the reasoning behind this? every other card game I’ve ever played lets you freely fail to find.
