I was able to redeem this player card from the website but it did not appear in my collections. Already contact Riot and they said they will be looking into this. Anyone had a similar experience?

I want to improve my aim, and deathmatch is just not for me. Spike rush is too messy for me to even process, and that's where I feel a 1v1 mode would be great. You hop in a quick match (best to 4?) and much like CSGO warmup phase, just duel...
