Free Speech says opposing heroes lose all abilities until after their next turn. My question is, once that turn has passed, do they regain only their printed abilities or do they somehow remember and regain any additional abilities they might have had at the time Free Speech was cast? My suspicion is the former based on the wording of both the card and Sirlin’s ruling in the card database, but it’s not explicitly stated.
Practical example:
Player 1 casts Metamorphosis, giving Vandy the Demon type, 2 +1/+1 runes, and the abilities of Readiness and Invisibility. Player 2 casts Free Speech, stripping Vandy of all abilities, but leaving the Demon type and the 2 +1/+1 runes. After player 1’s next turn, Vandy will either be a Demon with Readiness and Invisibility, or she will be a Demon that does not have those abilities and cannot regain them from Metamorphosis without first somehow leaving play to reset her types.
