Here's a big Spreadsheet I've made.[docs.google.com]

I would 100% insert a table here but I just don't know how exactly. So I just used a google spreadshit.

This is relevant for Challenger and Group stage (I'll probably update after the end of the tournament). So it's no hurry for current legends but they are on the list.

How to use?

First section represents Best chance to get a particular player sticker. Additional info: Opposing team, map, mvps of the player and total number of rounds. Just to find the game easier or to report a mistake.

Second and third sections represent an alternative pick. Attention! This is not the best chance but rather a way to get the most out of situation.

I decided two factors for that to be more important than just second-best chance.

Opponent. So if you lose, you can get a star sticker.

Map. Almost everyone agrees that best skins are Inferno, Overpass and Nuke, so if your chances are low, at least you'll get a better drop.

For example, I want Get_Right sticker but his best chance is ~22%. But it's against FURIA on Mirage. So I look at the other options wich are 12% Vitality+Overpass or 14% HellRaisers+Overpass. Let's say I don't want frenchies stickers at all, and as NiP lost that game, I choose the confident win against HR with hopes to get another NIP player and a decent skin.

These factors are highlighted with grey color in the chart. (The "starteam" question is subjective So use it with caution I just tried to be logical. For example G2 have only 2 stars while fnatic 3 so I decide them to be a "star team". I don't like it too much but it is what it is).

The second list of the spreadsheet is sorted by the best chance column. Where you can see... dennis at the first place and device on the second. No way device is missing even here!

So... About that golden D.i.c.k. (autocensure at work)) you want. Your best option is only 12% in the game against fnatic on Inferno. And it really is the best, as they lost that game by quite a margin so if you fail, it will be fnatic player most likely. If you want to get French player and try your luck with the Vitality game, but you can end up with malta sticker.

This guide was created in a hurry and free time deficit, so I'm sorry if there are mistakes. Tell me about some if you met them and I'll fix the ♥♥♥♥. Also I would like to make more options like win-loss but again have no time. But I'll try to include some shortly after IEM Katowice.
