very solid deck Hakeem but i would try to fit in some early defenders in case you can't rip a Pelakka to stave off the life loss from an aggro rush. i'd also consider
Ogre Jailbreaker since you're always gonna have a Gate. i'm not sure that deck needs Visionary, Wayfinder, AND Phyrexian Rager; two of those three would probably suffice. imo.
You're spot-on on the Wayfinder/Visionary/Rager package being overkill, but your suggestion of Jailbreaker was off my radar and it's really good (at least in theory). Let me explain.
Since this deck is an evolution of my Abzan list it has a lot in common; twelve gates, a bunch of early creatures that replace themselves, and a devastating group of bombs. The difference between the two lists, however, is that my Abzan has seven four-drops while this deck has none.
Why is this important? Because we're playing twelve gates. The typical way to curve out with Abzan is Gate/Basic/Gate/Basic which lets you play two two-drops into a four-drop as your first three plays. With the Jund list there are a lot more three-drops so it isn't nearly as easy to play Gates and curve out at the same time. Swapping Ragers for Jailbreakers fixes the curve problem while adding a creature that survives Anger of the Gods and bricks aggro much harder. I like the idea a lot.
Honestly, I'm surprised I missed that because Jailbreaker is a major pet card of mine; he's a big piece of my Grixis control list. Thanks Mythic, I'll test the list swapping Ragers for Jailbreakers and see how it goes.
