I used Bartender Bob’s “Stories Told” buff to give my Doppelgangster a +2/+2 buff. Clever, right? When I played him in the next match, though, the main Doppelgangster was a 4/4 but the two cloned Doppelgangsters were only 2/2s. Strangely, when I long-pressed a cloned Doppelgangster, it shows the “Stories Told - +2/+2.” buff text below the card, though the card is only a 2/2.
