MTG Salvation

You are correct, but instead of putting words as the mana colors in each group I just made de colors in words match the "nearest" mana symbol due to aesthetic reasons.

I made this circle with all guilds, shards and wedges to have a visual connection.

Don't know if its visible with the attachment option...

Revised list now with all suggestions and with MONK that I had forgotten...

Now with 11 classes The match is not 1-1 but Shaman feels more Temur...

UR (Izzet League) - wow MAGE
BW (Orzhov Syndicate) - wow PRIEST
RB (Cult of Radkos) - wow WARLOCK
RG (Gruul Clans) - wow HUNTER and SHAMAN
UB (House Dimir) - wow ROGUE
WR (Boros Legion) - wow WARRIOR
BG (Golgari Swarm) - wow DEATH KNIGHT
GU (Simic Combine) - wow DRUID
WU (Azorius Senate) - wow MONK
GW (Selesnya Conclave) - wow PALADIN

Better?

Guimas

It's also a good idea since shaman as elemental can have fire (R) or water (U)

A lot of MAGIC players algo play WoW or any other kind of mmorpg.

I thought of WoW classes and magic guilds and came to this list:

UR (Izzet League) - wow MAGE - due to Fire and Ice
WB (Orzhov Syndicate) - wow PRIEST - due to Light and Shadow
BR (Cult of Radkos) - wow WARLOCK - due to Fire and Corruption
RG (Gruul Clans) - wow SHAMAN - due to Elements and Nature
UB (House Dimir) - wow DEATH KNIGHT - due to Frost and Plagues
WR (Boros Legion) - wow WARRIOR - due to Protection and Haste
BG (Golgari Swarm) - wow ROGUE - due to Stealth and Agility
GU (Simic Combine) - wow HUNTER - due to Beasts and Control
WU (Azorius Senate) - wow PALADIN - due to Light and Protection/Control
GW (Selesnya Conclave) - wow DRUID - due to Nature and Balance

I know I forced 10 pairs and probably you may see another aspects of classes more relevant to put them on another guild, but let me know your opinion if you also like both games.
