Well, I like the term, we have now 3 different types of farms:
(Clear) Farm: 6*2 rares and 18 pillars/towers.
Pillars and mark are different from rares.
Example: 18 earth towers, mark of death, 6 Titan, 6 Jade Staff
Barm (thanks to KDZ): 6*2 rares and 18 pillars/towers.
Pillars and or mark are able to power the rares, meaning they can be used
Example: 18 light tower, mark of death, 6 miracle, 6 morning glory
Harm: 6*2 rares, some helping cards (mostly flying weapon), and pillars/towers
The helping cards are used to create a lot of danger, SoR can also be used to make a farm dangerous
Example: 12 air towers, mark of air, 6 Eagle's eye, 6 SoG, 6 Flying weapon
How about these definitions to keep the different farmtypes apart
