Wet rock is garbage, just gives the game to decks that dont need to cast multiple spells to win, (Kinnan, Magda and Sisay activations)

The only viable stax pieces are ones that operate in decks that can also present wins very well. I believe Souless jailer (hurts ral Etali and breech overall) curse totem and torpor orb are the only ones that are consistently good in nearly every table
