Question on Infection

Recently got the Rook City expansion. Got a simple misunderstanding, as usually the card says where the card should go.

Just curious if Infection comes off as a Villan Play card, do the Heroes get to decide which Hero gets infected?

True.  Infection is played next to the uninfected Hero of your choice.

Yeah - if a card doesn't specify exactly where it needs to be played/used against (ie if it doesn't say "Play next to the hero with the loest hp" or whatever), you can choose the target. So Infection can be played against any hero. If you have Infernal Relics, Gloomweaver's voodoo pins are a different story.

Thanks for the confirmation.
