It's OK. I mean it's not the best, I definetly learned much more in Card College, but if you learn it from Ninja 2 you SHOULD be able to do it for Triumph ok. He only teaches how to do it with Triumph. You won't learn from Ninja 2 how to take a deck and just do the zarrow shuffle and retain the whole order.
EDIT: I just rewatched it and he spends 33 seconds teaching how to do it with triumph.
