You should just silence these critics once and for all dude. As you say you can prove your theory using hsreplay and comparing overall popularity of decks vs matchups for specific decks, but it’s easier than you think, so here’s the step by step.
- google hsreplay and choose the first search result
- select the the meta tab->by class
- note down the popularity of each deck
- select the matchups tab
- go through each row or column and total the number of games for each deck type
- divide the number of games played against a particular deck by the total to get a %
- compare the % you just calculated to the deck’s popularity, that you noted in step 3.
Please post your results and lay the smackdown.
