cant play certain games?

so I have a full underdepths deck, but most of the games wont let me play...why is that?

 

You might have a banned rune I suppose, I don't know if anything in UD is banned though @Etherielin

 

how do I find out?

 

Check with eitherlin

 

If you're trying to play a campaign, some of them are alignment locked to Protectorate Factions (Forglar Swamp, Ironfist Stronghold, K'thir Forest, Savage Tundra) & Wrath Factions (Forsaken Wastes, Shattered Peaks, Sundered Lands, Underdepths)

 

Temple of Brutality is the only banned UD rune that I know of. That said, it's only banned in ranked play, so it should still be usable in campaigns. If you don't have Temple in your deck, then see the above post for help.

 

Post your build here.

 

Ethereal pool is also banned
