Loki has had enough. For whatever reason, Strange, Doom and the Sentry are on board and decide Odin is unfit to rule Asgard. They get a week to prepare some stuff before teleporting to the fringe of Asgard.

Some rules:
Doom can go ham, but no time travel.

Loki can likewise use the whole week but only with stuff he can scrounge up in Dooms Latveria.

Strange can ONLY take ONE artifact from his sanctuary into battle with him. The rest of his prep has to be in Asgard itself on the way to Odin.

Lastly, Thor is likewise in Asgard and can help Odin but is somewhere off in the fringe as well. Odin has a premonition of a looming threat an hour before the assasins arrive, so he is wary and cautious. They won't find him sleeping or whatnot.

Can they do it?
