I don't think you understand. As far as my elfball list goes, Larhril wins in almost exactly the same way, WITH ACCESS TO BLACK TUTORS.
A win with Ezuri for me looks like: create an infinite untap loop, make infinite mana, cast Ezuri, pump, win.
A win with Larhril will look like: create an infinite untap loop, get 10 elves, have Larhril/cast hasty Larhril, win.
Now, I get access to black, I can win at instant speed assuming a
flash outlet or enough elves to finish the table (tokens would help here), and I no longer rely on combat. Obviously, I'm going to need to do quite a bit of testing since I'm basically starting from nothing again, but I imagine this list is going to be very similar to Ezuri with a better tutor package, better removal, access to meaningful recursion, access to more draw effects, a less vulnerable win, and lesser reliance on luck of the draw.
Still probably too slow and too many parts for cEDH, but maybe not. This commander has me more excited than any I've seen since I first found
Scion of the Ur-Dragon.
EDIT: Also,
Shaman of the Pack and a bounce effect is an equally good alternate win condition, again without reliance on combat.
