Played Countess with Mirage, however didn’t receive any token cards from her battle cry (had only 6 cards in hand).
Her battlecry depends on having no neutral cards in your deck.
The obvious explanation is that your deck did have neutral cards.
Reno is a neutral card so he breaks pure synergies until you draw him
Why do people think Reno is a Paladin class card?
Reno changes to your class when you play him, so maybe they think he’s your class as soon as he’s in your deck? Or maybe they associate neutral cards with minions? Or maybe just wishful thinking. Beats me.
