It can be said that winning with a single team composition repeatedly in many matches is extremely challenging; if you want to climb the ranks quickly, you should avoid this playstyle. However, contrary to the opinion widely agreed upon by many players, the community has recently been sharing tips on how to effectively use just one comp to climb to Master rank.
Here is the widely shared playstyle:
Traditional Rebel Comp

Speaking of universes, this comp maintains mid-to-high strength across various universes like Tiny Pets, Neeko’s Universe, Cosmic Galaxy, Trade Zone,… Since this comp is strong in both early and late game thanks to the Rebel trait, and with Zed included, activating 6 Rebels to maintain a winning streak is much easier than before. Additionally, you can maximize the potential of items since there are many carries in the comp, so you don’t have to worry too much about getting “ks” on items while shopping.

Moreover, this comp does not heavily rely on rolling for 3-star champions, so if 1 or 2 other players are on the same comp, it’s not too concerning. Not to mention, this is a composition that is extremely underplayed in the current meta, making it quite easy to reach 2 stars.

Next, this comp is a hard counter to the hot meta compositions featuring Cassiopeia as the carry, as her damage over time is nearly zero while the Rebel shield is active. By the time the shield wears off, Aurelion Sol would have stacked a lot of rockets, plus Jinx would have activated her trait to obliterate the enemy team.

One player shared that he used the Rebel comp to achieve a winning streak of top 1-2 for about 10 to 15 games in a row, reaching Master rank, and then he… stopped playing. If not, his rank could have been even higher.

Here is a guide on how to use the traditional Rebel comp early to secure a winning streak:

The ideal comp at level 4, at this point use whatever you have, you can assemble items early to secure a winning streak. Suitable items include Infinity Edge for Blitzcrank, Blue Buff for Ziggs, and damage items like Giant Slayer or Guardian Angel for Yasuo or Zed (later transferring to Jinx or Gangplank).

At levels 5 and 6, besides Blitzcrank, you can choose to use Zed + Nocturne or Ziggs + Rumble (use whatever you have). This comp can quickly take down the enemy’s backline while continuously stunning the frontline.

When you reach level 7, you can choose to activate 6 Rebels as soon as possible, or you can choose to hold onto Rumble for Blast Shield and add Ezreal for Sharpshooter and Chrono. At this stage, patience is needed, and you should roll slowly using your income; if you have enough champions for defense, it’s better to save gold to level up to 8 and 9, as this comp becomes stronger with more champions.

When you reach the final composition, the most important thing is to position your champions so that Blitzcrank can hook the enemy carry. Another thing to keep in mind is to choose appropriate items for your carry champions, for example, Gangplank should have Guardian Angel (to avoid getting eliminated before using his ability), Aurelion Sol should have Morellonomicon and one tank item, Jinx should have Giant Slayer and one tank item or Blue Buff,…
With this composition, climbing to Master rank is within reach!
