would any one explain or it just a bug!
stealing Underbelly Fence with Seance doesn't give it Rush!?
while the rest of my hand were a priest cards! 

"From another class" refer to a mechanic that check your class vs your cards' class.

So, you need a non-priest & non-neutral card to proc this effect.

The effect works if the minion is on board. So no rush or +1/+1 if you only got priest cards in your hand after summoning it.

Works as intended. This type of cards checks your hero, not where they was. Like playing warrior hero card you will become warrior and Tess wil replay all rogue cards.

depends on your class. Also, it doesn't count itself, neither does Vendetta (arguably less coherent)
