Skarz-Ashada, Chitter Queen

Reach, protection from blue
At the beginning of each opponent's upkeep,
that player exiles two target cards from their
graveyard. If they can't, That player sacrifices a
nonland permanent for each nontoken spider
creature you control.
"If Clan Ashada cannot be repelled, perhaps they can
be appeased. For now."
- Lord Ryker
