Well.. D-Shift is pretty useless on master at the moment. I have not encountered any of those myself but a turn 8 D-Shift play would be way to slow due to Aggro decks, consitent decks and some other stuff being used. Besides that D-Shift's win rate was under 50% before it got nerfed!
btw playing D-Shito in rotation will be impossible
While the winrate is lower than 50% for dshift, it’s the nature of the deck that called for the nerf. The way Dshift works makes favoured matchups extremely favoured and due to it’s speed and lack of interaction, makes even unfavourable matchups winnable. The game isn’t fun or healthy when you get matched with an instalose matchup 40% of the time. Supposedly your deck has a 50% winrate against anything but Dshift you will win about 30% of the time on average thus making the nerf necessary as it warps the meta too much and stomps out decks that can win as fast as turn 7.
