Beta Cuck Renekton
Let's make like the last stage of grief and accept that everyone is a carry this season and possibly every season after this. Teams - ALWAYS - have enough damage. Always. It is assured. Braum Janna Taric Soraka Zac? Yeah that's enough damage. Taric builds a Triforce, two of them run DH and they're good.
Renekton wins lane then loses game. It's just what he does - everyone knows that and only beta scrubs would try anything else. How about we do the opposite? Let's assume every single game that our solo queue teams will be a non-stop parade of 4 squishy carries that would secretly appreciate a team member that lets them farm as they group and possibly die in every single teamfight but would never say it as that would imply they ever needed help with anything in their life. They'll reward us with ? pings and "why Comet?", which we can translate as "thank you so much for being the backbone of our otherwise degenerate team".
The most non-alpha thing one can do is run both Conditioning and Overgrowth, so that's exactly what we're doing. Remember how Camille takes Comet to help deal with laning phase? Yeah we're doing that too by Q-ing our lane opponent immediately when we get into range and then turning tail and running. We'll just keep doing that, and W+E'ing away from anyone that gets uncomfortably close. This way we put up a fight against anyone in lane that isn't taking Unga-Bunga Conqueror. Comet procs from R's AoE as well so it'll do ~7% of your champion damage lategame which ain't awful as opposed to others.
Teleport is our icing on the beta cake. Start Longsword +Refillable against anyone that can be reached with Q, and 3 Beads + 1 pot against anyone else. Beads sell for 105.
The Builds: 1.) Tiamat -> Sterak's This is our go-to as most teams don't even have someone that can remotely take any damage without dying. Sterak's can be played around but is still ridiculous.
2.) Dblade(s) -> BC Black Cleaver really needs no introduction. It's a little clumsy to build, though.
3.) Dblade(s) -> BORK If by some miracle our team already have multiple tanks and supports, this is quite viable.
After this point we want to build STRAIGHT tank for at least 2 items, usually 3.
DMP/Sterak's/Stoneplate/SV/Knight's Vow Be careful building Sterak's as we aren't tanky until we finish it. Knight's Vow is maximum over-beta and should only be considered if we have someone of T1-magnitude of alpha on our team. If they wouldn't spam-ping us that we're sapping minion exp from them then Knight's Vow isn't a worthwhile purchase.
Lategame items are where we can press our advantage, assuming your team of 4 squishlords haven't been facechecking the enemy jungle trying to 1v10.

Congratulations - you now know how I've played games all the way up to my plat promos this month. If you don't like it, guess what: so does literally no one else! I get made fun of for not running PTA or Conqueror by someone every single game. But that's okay, because I am a Beta Cuck Renekton. Downvotes will be fine too! Life's good.
This is probably my last LoL mini-guide ever or LoL guide in general as I am clearly not alpha enough to try to solo kill the entire enemy team in this team-based game. So cya. Or not; we'll see if Riot finally removes the Resolve tree from the game or not.
