Mercenaries stealth broken interaction

if you play hearthstone for as long as i do you get used to expecting certain interactions.

im trying out my new pvp comp that is built on trying to counter other comps.

im opening with malchezar, arana, and garona. and i can swap all 3 thanks to maestra.

my enemy plays valeera. but my counter to her is chromie on bench with stroke of midnight.

in first game i got valeera to 17 health thanks to malchezar check your weapons.
next round chromie and i used maestra 3rd ability on unit adjacent to valeera to kill her.
she was stealthed so the dmg ignored her and went to brightwing (yeah 5 v3 merc build enemy)
why does it skipped valeera?

I don’t believe I can test or review your situation thoroughly, though, so I suppose a prompt response after a cursory examination is all I can offer for now.
