I think you should focus on tempo. Vs control, vs many board clear, gain tempo and try to kill them early is better than keep it to use the “Echo” keyword.

Where is the rarity stone?

Yeah, I understand that a bo3 with “sidedeck” is cool. But now everyone must play and watch 3 game, same matchup with a little “tweak” every match. It’s more competitive now for the tournament, but somehow less interesting for me to watch. But I still think this change is neccessary.

But now player can only play 1 class through the whole tournament?
