Mortal Kombat is and will always be the best video game adaptation . <| sep |> I think getting used to the fetches you play also plays an important role . Obviously tarns are better than mires but I guess you ' ll play your deck anyways even without the tarns and you ' ll be right to do so . You ' ll get the habit to use first your mires to get your blue shock and you ' ll be fine . These kind of questions , which are relevant to maximise the potential of your deck are , in my opinon close to details . You have so many other ways to increase your win percentage , such as knowing your game plan inside out against every decks . So don ' t worry , you ' ll be fine ! Play with your bloodstained mires , learn how to be good with grixis delver and I guess you ' ll be able to borrow tarns for your next RPTQ GP I have been playing with wrong fetchs al the time , it ' s not optimal but it ' s okay .
