# Champions Combinations

## Play Rates

In this section I provide the play rate of which combinations of champions (plus the regions) are used in a deck. The champions showed right before a game starts for example. Right now it’s a simple approximation of the archetypes played in the ladder as such information is not restrictive enough.

## Day by Day

Highlisting the top10 most played decks (at the moment of the last game played).

## Win Rates

Tie games are excluded

### Meta Decks

Win rates of the most played combination of champions. Play Rate >= 1%

### Underdog

Top Win rates of the least played combination of champions. Play rate $$\in$$ [0.1%,1%)1.

# Match Ups

## Match-up Grid

Just a different way to print the table of the MU grid, more an experimentation

# Deck Structure of the week

## Viego (FR/SI)

Let’s start with Viego and the other star of this event: Akshan

## Viego (SI/SH)

Let’s start with Viego and the other star of this event: Akshan

## Viego (IO/SI)

- Play rate: How often a card is included in this class of decks / the table is order by this column.
- 3/2/1 is the relative and absolute frequency of the number of copies in the decks that plays them
- Frequencies from 50% to 100% are colored from shades of green to white to identify more easily the highest values

# LoR-Meta Index (LMI)

The LMI 2 is an Index I developed to measure the performance of decks in the metagame. For those who are familiar with basic statistical concept I wrote a document to explain the theory behind it: , it’s very similar to vicioussyndicate (vS) Meta Score from their data reaper report. The score of each deck is not just their “strength”, it takes in consideration both play rates and win rates that’s why I prefer to say it measure the “performance”. The values range from 0 to 100 and the higher the value, the higher is the performance.

# Cards Presence

## Play Rate

It seems that not even Twin Disciple can beat Sharsight

## Forgotten Cards

Cards that couldn’t find place even in a meme deck.
