Hearthstone: Factions Expansion

Album Link - http://imgur.com/a/UdGVQ

So I had this idea that there'd be an expansion where players join a faction. Factions would be released in a cycle, much like the current packs/adventure cycle. Throw in a handful of factions every few months and you keep the money rolling in.

The general idea would be that each player could be a member of ONE faction at a time in any given deck slot. It would be chosen at the start of making a deck, but could change at any time like card back. Joining a faction would give you friendly status with that faction, and then as you play against other people you level up your faction level.

It's almost like a sub-class. Players could change faction whenever they wanted and not lose their reputation BUT they would not be able to use faction cards in that deck. To clarify, each <b>deck slot</b> would have its own faction, to avoid having to switch around between each match.

Generally speaking each faction would give some "feel" of another class without directly making it feel like that class, because there are no spells. A players' faction would show up to their opponent, so you can kind of guess what their "sub class" is.

Faction rewards would go as following.

*Friendly - Two copies of two common cards

*Honored - Two copies of two rare cards

*Revered - Two copies of two epic cards

*Exalted - One legendary

The factions are based off in-game factions, but I stopped playing around WoD so haven't thrown any of those in. Some honorable mentions are The Tillers, Timbermaw Hold and Sporeggar.

Please do tell me what you do and don't like about the cards, and the idea of factions themselves as it may be an idea I run with in a digital TCG I'm working on.
