If a trainer card states that it removes 60 points of damage, can you use it to remove 50 points or less of damage? I have one card that says up to 30 points of damage, so I know I can use it to remove 10, 20, or 30, but this card states 60 and does not use the words "up to".
In Pokémon, there are some core rules. Two of them are relevant here:
- "Do as much as you can" -> you can heal less than given amount of damage
- "Every card played must have some effect" -> you can't heal zero damage
