I don’t play much modern. I just lack the knowledge of the format. I’ll probably accumulate that over time, but I’m not in a real hurry. I’m much more interested in the formats with limited cardset I can master on my own. Since I don’t have that much time, I’d much rather stay with standard and block, as well as limited.
What I do know is that aggro is pretty bad in modern. Sure, there’s affinity, but that’s pretty much it. What I’ve heard from more active players is that affinity is just so good that it simply displaces all other aggro decks. Well, at least to me this means I should be playing aggro, and not affinity.
