Also, someone finally explained Pendulum cards to me today... My first thought was "Oh my god, the game is officially broken." but then, after he finished, my thoughts expanded into "This sounds like one of the development team wanted to make their own card game, but since they weren't able to, they shoehorned it's main mechanic into Yu-Gi-Oh! instead.

Essentially, you now have what are called Pendulum zones, a left one and a right one. You can special summon from your hand any monster that has a level inbetween the levels of the Pendulum monsters in those zones.

So, all you need to do is get a level 1 in one zone, and a level 10 in the other, and you can special summon your entire hand for no cost.

So yeah, after a long discussion, we came to the only logical conclusion... The creators are now bored with Yu-Gi-Oh! and so they have decided to break it.
