It's hilarious that this actually works, but as far as I can tell the strategy doesn't actually hold up that well.
In MoF, you have a net gain in lives up through Kanako's battle, and the real challenge is to have enough lives to get through it. This necessarily means that you can't just spam through the game unless you're really good at the final card. Which apparently you are, Drake.

In my first 1cc attempt, I got to the last card with 4 lives, and
still lost. So, no, people trying to beat MoF Normal shouldn't use this strategy.
