Which is more viable?

[DimirOverlord1300]

Oloro life gain or sharuum the hegemon artifacts?

[Malachiracer]

{Oloro, Ageless ascetic} is much better, check the deck I posted called Oloro esper Eternal bargin

[DylanW18]

Personally both. Sharuum is more artifact creature Aggro heavy and stuff where as Oloro is more midrange/combo. Just depends which you prefer

[Gorzo]

Both are perfectly viable. Oloro/esper life gain works very well (White for gain, Black for drain, Blue for card draw), and Sharuum is quite well known for artifact combos.

Both are completely viable. Except I always use commander decks that don't care about your life total. So Oloro loses out on that one because there are a ton of ways to die in commander that arent life total. In this way I think that Sharuum is slightly more viable because the commander itself is a combo piece.

The big issue I see with oloro is all the spells that prevent life gain. It almost shuts down the deck completely
