When you consult the Kami ...
Make it so anyone can consult the Kami [or ancestors or Buddha], I mean, they're right there all around us at anytime. The Shugenja are just better / way better at it / less likely to piss them off / get other awesome moves (like Brainers.)
Also, make it meaningfully different from Open Your Brain and the Psychic Maelstrom. Both in terms of mechanics a flavour.
Like, the Deadwood hack got this:
When your mind is besotted with your particular pleasures (booze, opiates, whores, gambling, violence, righteous anger), you gain revelatory insights amidst all this squallor. Roll+wild (or whatever) and pontificate, in brief or in full, about the nature and truth of things. On a hit, the MC will seize on something you've said and ellaborate on your insight. On a 10+, they'll straight-up tell you something you hadn't realized before. On a 7-9, they'll hint at the answer to something that's been vexing you. On a 6-, some truth will set you free, but not this truth. No, this truth is gonna shove you right back into the mud.
And tentatively Bulwark has/had this:
WHEN YOU SYNC WITH A NODE
13-17 +1SYNC 11-12 +0SYNC 08-10 -1SYNC
MC: #TAG AS APPROPRIATE
WHEN TRY TO GET SOME INFO
ONHIT GREP SOME DECENT INFO
13-17 TAKE +1SYNC 11-12 +0SYNC 08-10 -1SYNC
So, you can see that both those moves fit into the same mechanical spot as Open Your Brain, but are fiction-first in terms of their implementation and colour.
