Read

Every recent match of the opponent, from their main and second accounts, ranked play and events.

Sort

Their decks by game slot: what they open with, and what they switch to after a win or a loss.

Plan

After each game, the burned decks come off the board and the plan for the next one is what is left.

Burn their decks

In a Bo5, a deck can be used only once. Tap the decks this example opponent has already played and see what is left for the next game.

Example opponent, numbers made up for this page. In a League of Legends draft or a Brawl Stars map pick the same logic runs on picks and bans.

5 decks still openshare of their last 40 series

Nothing burned yet: they open with Hog Rider almost half the time.

Tools I built

Based in: Germany
Analyst since: 2019
Works in: Python and SQL

I am Till Oscar Jacob, known as Rukawa. I have analysed Clash Royale for teams since 2019, and in 2026 I prepared Morten and Viiper for every match of their CRL season.

I write my own tools in Python and SQL, with AI assistance, and check every number against the raw match log. For 2027 I am looking for an analyst role with a League of Legends or Brawl Stars team.
