When a friendly minion dies while Sonya is in play, a 1/1 copy is added to the hand.
The effect of Crystal Core, turning minions into 5/5, does not apply.
Thus, the minion is 1/1. This is expected behavior.
However, while the token view displays the real stats (1/1), the zoom view still displays the minion’s stats as 5/5.
