Thank you all.
I was more in thinking Det/Crit, because for WTM Crit is usually waste when it happens and not happening when I may want it. And Det is just flat out increase on everything. My SCH is in love with Crit on other hand, while AST is more neutral about it.
Piety... well, only AST have Mana issues, but extended lucid usually help with that, and if really starving I would forgo roading refresh card and eat it myself. Though that is rare.
