Sharuum the Hegemon is more of an Esper support card than anything else. Although it's a 5/5 with flying, its effect is designed mostly to bring back an artifact that's been destroyed.
This card would work much better with flash, since then you'd be able to bring back artifacts as soon as they're destroyed. Also, the fact that it only revives one artifact makes choosing which one difficult.
To conclude, Sharuum the Hegemon leaves something to be desired, but it can be quite helpful for bringing back your artifacts if necessary.
