Flipping Set cards would imply forcing their activation (which gets into all sorts of ruling issues). Unless you want that to happen, you should add a clause that flips it back face-down again. And probably add a Once per turn clause onto that, otherwise you can just S/Ts or cycle your hand, or trigger FLIP effects infinitely, or summon every monster in your Deck. I'm not even gonna go into the whole 'everything you play is now a S/T card' clause that you've somehow fit in there.

God knows why you gave it 2400 ATK. It's already a silly card. Utility Xyzs really shouldn't be above, say, 2200 ATK. I'm sure that Special Summoning effect looks broken too. Not sure how, but it probably is.
