So I’m getting back into it, or that should be I’m going to, and have some questions.
When I last played to any extent there was the stack, that seems gone. So where are the rules these days?
I note also my dci number is now meaningless, is there no ranking anymore?
I live in the middle of nowhere (Scotland) so wonder if there is anywhere I can check up local clubs?
Also any suggestions on where to find deck ideas and where should I start, core and which expansion’s?
Stack still exists and I think those rules are mostly unchanged from 2013.
I haven’t played tournaments in a while, but instead of the DCI I believe they are using the Wizards Account. If you have played Magic Arena then you already have one, if you haven’t it might be worth installing and playing a bit to get a refresher on the game and see some of the recent sets.
There’s a store locator that may help find some place to play: https://locator.wizards.com/
Finally, about building decks… first find out where and against who you’re going to play. Since there’s a bunch of different formats (Legacy, Modern, Pioneer, Standard, Commander) it’s best to find out what is popular at the place you want to play before building a deck.
