One of the rituals that I do is 'spin' the pack counter-clockwise before I drop it! xD

I know it is silly and ritualistic, but I do it every single time! Whatchu got for me?

Before opening the pack, I sacrifice three sheep.

Sheep Sheep Sheep 

I offer my soul as an offering to the demons of Salazaar and the Great Void known as "meta". I have never opened a pack with a legendary because the God Emperor Brode blessed be his RNG hasn't deemed me worthy.

I usually w8 until the pack starts shining then immediately throw it to the center , kinda works sometimes xD

I have my fiance open them.

Not necessarily a ritual, but if she gets a little enjoyment out of me playing the game, she is on my back less about the time I am spending on it! 

i sacrifice ton of money

I used to do the ''spin'' but eventually I became sick of it, especially when opening large amounts of packs so nowadays I just rush through them.

My packs get moved in a straight-ish line, but in a "pilgrim step" fashion. That is, like first taking two steps to the right, then a step to the left. Usually I repeat this 2-3 times before dropping it. Like OP said, 

I know it is silly and ritualistic

but since the first time in this way was a lucky one for me, I keep doing it :D

Not really, but before I open it I tell myself not to get too excited if I see an orange glow, because more often than not I'll get an unplayable legendary and then I'll be disappointed. Then I open the pack and actually see the orange glow and I'm so excited that I immediately click it and I become disappointed seeing it's an unplayable legendary. =/

I usually buy them before I open it.

Yes, do a couple of circles in counterclockwise and it give me many legendaries until un'goro release that it failed hard, but now i just draft in a straight line

I too sacrifice a ton of money :/

I drag them to the middle so i can open them

I count to 40.

I open mine in a 5 point star pattern.  Bottom left to top right to.....well you get it.
