Evoke and Flickering
Asked by andypants040 7 years ago
Similarly, if I remove the last time counter from Aven Riftwatcher can I flicker it before I have to sacrifice it?
Short answer: Yes you can.
Shriekmaw and Mulldrifter, when cast with evoke, create a second enters-the-battlefield trigger, in addition to there normal enters-the-battlefield triggers, so you can react to it, just like to every other trigger.
Aven Riftwatcher has Vanishing. This means, besides that it enters the battlefield with 3 counter, that it has the following two abilities:
"At the beginning of your upkeep, if this permanent has a time counter on it, remove a time counter from it,"
"When the last time counter is removed from this permanent, sacrifice it."
You can react to both of those triggers with a flicker effect.
