2017-02-09: The value of each X in Walking Ballista’s mana cost must be equal. For example, if X is 2, you’ll pay to cast Walking Ballista and it will enter the battlefield with two +1/+1 counters on it.

2017-02-09: If Walking Ballista has been dealt damage or had its toughness reduced by an effect, this limits how many times you’ll be able to remove +1/+1 counters from it in a single turn. For example, if it has three +1/+1 counters on it and has been dealt 1 damage this turn, it will be destroyed immediately after you activate the ability a second time and you won’t be able to activate it a third time.
