Let's put it this way. Some cards are SO mandatory that they've been hovering around 90% usage rate or higher, for years. The current meta has shaken this list up quite a bit and some cards aren't quite as prolific anymore since they don't do much against the new hotness. Still, at least 20% of someone's deck is basically guaranteed to be the same as anyone else's. Unless you're running some JANK you're always taking the same cards for everything and then the rest is just dependent on meta and what works for your deck specifically.
