I hope everyone is enjoying the league, I know I am.
To begin with I was losing a lot of matches, but now I’m doing better and catching up with the leaders.
I thought it might be worth writing down my thoughts on the subject so that if anyone here is feeling a bit discouraged with their results then they could take some inspiration and maybe do the same.
The first thing to notice is that several tribes are much stronger than others. Elves quickly grow to an unstoppable swarm, as do goblins. My flying Illusions deck lost to Elves. Having 9/9 flyers looks good in theory, but is way too slow by comparison, and mono blue has no way to deal with swarms. My Faerie and Elemental decks did no better.
Now I selected Illusions because I always liked that deck in standard, but in all honesty it was never going to win so long as Elves are around. To win, I needed to forget about playing my favourite tribes and fun tribes and either play Elves or something better.
To beat swarms you need wrath effects, which means playing white, black or red.
The other issue is speed. If I can keep the board clear and hang on to my life total then I have lots of time to play slow creatures and to win slowly. Mr Moto has an elemental deck that is very successful like that (watch out for the blinking shamblers). I decided to try and be even faster than the Elves instead.
I ended up with a mono red Goblin storm deck. This obviously includes 20 Goblins, but also 4 Martyr of Ashes to deal with swarms (not so good against flyers note). It’s very fast, and can just win on turn 1 or turn 2 sometimes.
A final note on deckbuilding. Your deck has to play well every game. Always use 4 of each card unless you have a good reason not to (toolkit control deck). Get your land right, especially if you’re in more than 1 colour. You have all of classic to choose from, so don’t pick a bad card if there’s a better one to be had, they’re all common and generally don’t cost a lot.
Hope that helps, and good luck.
