Flickering on wraths

[EonAon]

I know that flicker and blink are two different mechanics, but will a flicker effect save something from a wrath effect or would only a blink effect with a eot save things?

Technically, neither flicker nor blink are mechanics - they're colloquial terms that are used both interchangeably and inconsistently. Flicker and Flickerwisp do different things, as do Momentary Blink and Blink Dog.

That said, if you're talking about how they interact with Wrath of God and other sorcery-speed removal, yes, you'll need an exile-until-end-of-turn effect like Ghostway. If you use Cloudshift or another effect that returns the creature immediately, it will return before the board wipe resolves and die.

In general, let's say we're talking about Cloudshift versus Final Judgment. If you were to cast Cloudshift targeting a creature you control with Judgment on the stack, Cloudshift would resolve first. The creature would be exiled and returned to the battlefield all within the resolution of that spell. Then Judgment would resolve and exile every creature, including the one that just was exiled and returned to the battlefield from Cloudshift's effect, because it isn't looking for any particular set of creatures - the creature in question is on the battlefield when the spell resolves, so it's exiled. By contrast, Cloudshifting a creature that was targeted by Murder would make the Murder fail to resolve for lack of legal target, because its target was a specific object that no longer exists.
