SoA goes through almost all DR, while at the same time limiting the gap that ability-reliant cards can create. This is why SoA clans in general are strong.
Roots have attack manip which allows them to fight most clans more or less as equals... Enabling them to either hit hard with a big gap card (like
Gretchen or even
Ojibway) and then wall, or to ride out their damage reducers and hope for a powerful 3rd/4th turn counter.
GHEIST, on the other hand, just focus on hitting you in the face with both of their disfigured, meaty hands. Cards like
Dolly,
Methane,
Wardom and
XU52 hit for devastating amounts of damage. They can be a very strong
ELO clan, with all of the cards I listed being at a slight advantage against ability-reliant heavy hitters, like
Askai. Your opponent will be tempted to pill up to make sure those big threats don't sneak through early. Heaven forbid a
GHEIST player catches you bluffing...
Hope that helps.
