Ban Eldrazi Temple.
It's pushing out decks that would have better game against Death's Shadow.
Turn 2 Thought-Knot Seer is bad and wotc should feel bad. Happens with some degree of consistency
Eldrazi Aggro is 12% on that chart, just 1% under Death's Shadow.
At the end of the day, Death's Shadow is a fair deck. It's simply well positioned in what is actually still an Eldrazi clusterfuck.
Ban Ancient Stirrings.
Tron, Eldrazi Aggro, Bant Eldrazi, Lantern all use it.
It would be enough if it could get you a creature or land, but then it also goes and allows you to get an artifact too.
It can give you extra consistency for a turn 2 Chalice of the Void to lock the game down, grab Ugin or Oblivion Stone or Engineered Explosives to wipe the board, or give selection for extra muscle like Walking Balista or an Eldrazi. In some builds it finds you Basilisk Collar (For Balista) or Eldrazi Displacer to prison-out the opponent.
Notice the solution to the T2 Chalice consistency is Thoughtseize, which puts Death's Shadow over other options like burn.
Death's Shadow is also a deck that gives a big fuck about tempo advantage so it naturally combats the opponent paying G every possible turn.
Every deck that wants to answer Death's Shadow must also somehow answer Tron AND Eldrazi. And also do decently against the rest of the field.
When you factor together Colorless Eldrazi, Bant Eldrazi, Tron and Lantern, you have well over 15% meta share.
Eldrazi Temple, Ancient Stirrings, or both, are in each of those decks.
