Nekugal, Praetors' Mistake

Deathtouch, haste, eradicate 1 (Whenever this
creature attacks, defending player sacrifices a nonland permanent.)
At the beginning of your end step, dwindle.
(Choose any number of permanents and/or players,
then remove from each a counter of a kind already
there.)
"We escaped together, forged together, now we flee from
our mistakes."
