{T}: Unruly Catapult deals 1 damage to each opponent.
Whenever you cast an instant or sorcery spell, untap Unruly Catapult.
In a Two-Headed Giant game, Unruly Catapult's activated ability causes the opposing team to lose 2 life.
Players can cast spells and activate abilities (such as Unruly Catapult's own activated ability) after the triggered ability resolves but before the spell that caused it to trigger does.
Unruly Catapult's triggered ability resolves before the spell that caused it to trigger. It resolves even if that spell is countered.
