My "un-Punishing Jund" list is four cards off of that maindeck. I run -1
Grim Lavamancer, -1
Life from the Loam, -1
Phyrexian Arena, -1
Maelstrom Pulse, +1
Lightning Bolt, +1
Abrupt Decay, +1
Thoughtseize, and +1
Hymn to Tourach. I treat the three
Bloodbraid Elf slots as flex slots; I've experimented with BBE, 2
Garruk Relentless,
Sylvan Library #3, 3
Grim Lavamancers,
Huntmaster of the Fells, singleton
Life from the Loams,
Maelstrom Pulses, the works. I'm never really satisfied with those slots.
How has
Phyrexian Arena been treating you?
I agree with how strong
Kolaghan's Command is in the format. It is almost always a blowout for me.
I'm in the same boat with regards to
Grove of the Burnwillow. Grove-less Jund does get a better manabase than the
Punishing Fire version, but I'm not convinced that it's a better deck. However, without $200 to spend on Groves, I've been very happy with the "Un-Punishing" Jund lists.
