EDIT: It's also worth mentioning that mono white D&T has a good Eldrazi Tron matchup, in no small part thanks to the eight wastelands with pressure to back them up.
Between their land disruption, hard removal, creatures with protection and/or evasion and vials to outmanoeuvre them, D&T has a really good death shadow matchup.
Even without Arbiter it's really easy to make them run out of basics or to just cut them of a colour entirely.
So Death and Taxes is Death's Shadow's biggest enemy?
Can anyone explain a bit? Out of the modern loop.

Okay, so Grixis Death's Shadow runs 18-19 Lands, but of these, only about 6-8 are Mana producing. It's possible for Death and Taxes to lock Grixis out of their Mana producing lands+activating Fetches with the Leonin Arbiter/Ghost Quarter Interaction(which basically is a 2 card strip mine)
