Daphne is playing Arakni, Marionette against Velma, playing Valda, Seismic Impact. Velma controls a Leyline of the Old Ones.
On her turn, Daphne plays codex of Bloodrot and the turn passes to Velma. Velma goes straight to her end phase, triggering both the Bloodrot Pox under her control, and Leyline of the Old Ones’ self-destruct effect.
If Velma stacks the triggers such that the Bloodrot Pox resolves first and she chooses not to pay the cost, does she:
A) Create a Seismic Surge?
and
B) Keep her Leyline around?
