Spark Rupture

A planeswalker affected by Spark Rupture loses all abilities it has, not only loyalty abilities. The resulting creature may gain abilities after Spark Rupture enters the battlefield.

In some unusual cases, Spark Rupture may enter the battlefield during a combat in which a planeswalker has been attacked. In such a case, that planeswalker will be removed from combat. If blockers haven't been declared yet, the resulting creature may block. Creatures that were attacking that planeswalker remain attacking and can be blocked, but they won't deal combat damage if unblocked.

The resulting creature's power and toughness will change if the number of loyalty counters on it changes.
