There are plenty of plays that can get you in a winning situation with just a few specific Dragons like: Goldspan Dragon Ancient Copper Dragon Hellkit Charger With Goldspan Dragon and an Ancient Copper Dragon out, you can generate tons of Treasure tokens and then make bonus mana off of them
Not too many of those cards were critical things to deal with, only really Jitte is super savage that you can't take it
Every upkeep, you get a free impulsive draw (exiling cards off the top of your library and being able to play them that turn), but then, for each land card you exile, you get a 3/1 dinosaur token, and for each nonland card you exile, you get a Treasure token
Until then, we have these leaks to ponder
It is better disruption against most other kinds of deck than most other symmetrical draw effects too
