Hi eveefarmer87,
The rewards haven't been sent out yet. Here is the answer from the FAQs:
#Who's eligible for rewards?
Everyone, but there’s a little fine print:
- For the Pool Party icon and Pool Party Mundo, you’ll need to contribute points during Team Up Week.
- For the Mystery Champion, you’ll need to connect League and Facebook.
- For negative players who won’t unlock Pool Party Mundo or the Pool Party icon we took a look at an accounts recent history (February to now) with LeaverBuster, bans, and chat and ranked restrictions to make the call. We expect the vast majority of players to be eligible for the rewards.
#When exactly do I get stuff during Rewards Week?
It’s a little tricky to turn all this stuff on at once, but everything should be granted by 6/27. The only exception is the Mystery Champion, which will roll out by 7/1.
So yes, you'll be eligible for the Mystery Champion. But I would highly recommend teaming up with 4 other people at least once so you can qualify for the other rewards as well.
