I’ve sort of being looking forward to this, but there’s a problem. There just isn’t anything that would make a pirates deck better. I mean, there’s a couple of really strong Pirates. I like Warsail Marauder and Dire Fleet Daredevil, but they both have problems. The Marauder’s ability just doesn’t do much, if all creatures you control already have evasion, and Daredevil is of the wrong color.
First thing you should always do when brewing decks is figuring out what you can do with the mana. Of course, only a select few actually do this, because it’s much more fun to start with those interesting cards or synergies. Still, this is the way you should do it. (Yeah, I don’t either.)
