This clever loop turns Woe Strider into an infinite sacrifice engine by feeding it Obstinate Gargoyle over and over again. Normally, persist would put a -1/-1 counter on the Gargoyle when it returns, permanently locking it out of coming back a second time, but Vizier of Remedies steps in to completely neutralize that drawback by reducing the applied counters to zero. Because the Gargoyle returns with no counters whatsoever, it can be sacrificed to Woe Strider endlessly, letting you trigger death effects, enter-the-battlefield triggers, and infinite scry 1s to sculpt your draws.
