Mainstay's block power

Hey guys and gals,

I have recently been playing with 'The Sentinels' and been playing 'Mainstay's' block power as if it reduces damage to all heros. It says "Reduce damage dealt to all your hero targets by 1 until the start of your next turn."

However, I then watched a video uploaded by the lonesome gamer, and he was playing it as if it affected only the Sentinels team, not ALL HEROES as it states on the card.

Anyone care to tell me which is correct?

Cheers :)

"Your heroes" means only The Sentinels.  (Confusingly, this is true even if you're playing two heroes at once, as is suggested for when you have only one other player.)  Another player's hero is not "yours", and if you're playing two heroes, you pretend to be two different players, one controlling The Sentinels and the other playing whoever else (I recommend Legacy).  Thusly, Legacy is not "yours" when you take your Sentinels turn.

Thanks Unsafe_Bet :)
