I tend to run:
1
Grafdigger's Cage2
Nihil Spellbomb
I often had a MD Bog with Knight, but at the moment it'll be cut; so I'm unsure if I'll be happy with my composition of just those next to DRS. Nihil Spellbomb >>>>> Relic of Progenitus IMO. The reasons being that
it's live T1 and you don't have to hit yourself (which with running Goyf or KotR, you want them big); further you don't have to leave mana up to pop it; only to get the cantrip. I may add a pair of Surgicals, but I don't know. Relic/RiP are for non-Goyf/DRS decks for the most part.
I will say that if you ran a Loam or two in the side you'd have a much better game against Jund. They're so mana heavy (Pfire, BBE, Lily, Hymn) that locking them out is cake. Also, Lingering Souls is quite amazing against Pfire (simply because it takes so much effort to remove.)
