Much like yugioh , shadowverse has some extremely onesided matchups as a result of how many unique mechanics and playstyles there are . Dshift rune vs seraph haven is one of them . Personally i think its extremely unlikely for any haven deck that isnt storm or an elana haven that draws perfectly while rune never gets petrify to SMOrc down dshift before they have their combo . If you are playing seraph , your win condition actually has nothing to do with the board state and so if your opponent isnt playing any followers , you actually dont need to either . This matchup is literally a race to an otk , albeit in different ways . If you get some nice card draw you are very likely to have everything you need to instantly win on turn 9 . On the other hand dshift needs to constantly cast spells to eventually reach her win condition on turn 79 . The key is that dshift MUST run removal spells . They cannot mulligan them away under the assumption that youre seraph because what if youre actually playing storm ? Not keeping removal against storm haven would be suicide . This means that your opponent will play towards something that you are not . If you dont even play any followers when you dont need to only time you would really need to would be to kill merlin , cards like wind blast , kaleidoscope , and fire chain become extremely useless . They wont even be able to cast them if there are no targets , which means less spellboosting and slower draw power from fate . Remember as seraph haven the opponent leaders defense pretty much never matters because your win condition is an auto win . The only reason you would ever need a board is to make sure the opponent doesnt kill you first , but thats not how dshift works . So in summary , mulligan for draw power and dont play any followers that you dont need to . Dshift will end up with many dead cards which delays their win condition , while your own remains rock solid at turn 9 .
