Thanks for the post @threesteps! I was only made aware of this awesome mechanic recently, but since their discovery I've definitely got a couple favorites now.

I think my top favorite would probably be the 'leofinance' tag, followed by 'neoxian', 'proofofbrain' and a couple other more like 'archon' and 'battle'.

I'm still experimenting, but these have definitely been pretty good to me!
