Which will get you to legendary?!
my guess is that wild is easier, but I’d be absolutely shocked if someone who can reach legend in the easier mode can’t reach it in the harder mode as well.
Wild offers you more options in building a deck and some of those options can be superior to what Standard can offer you. However the amount of things to keep track of can increase substantially.
Standard meanwhile offers a more limited selection where the meta only usually includes a couple of big hitters to really keep an eye on, so there’s less focusing on learning tons of matchups and more time spent on learning to pilot your deck. At the same time however there’s less answers available to you as the card selection is more limited.
In the end it comes down to whether you want more options at the expense of having a higher learning curve VS having a lower curve at the expense of having a somewhat limited selection.
Play secret mage in wild, it makes it really easy to get to around rank 10
