Forum:Shadow-Imprisoning Mirror against Reptilianne Naga and Spirit Reaper

I understand that Shadow-Imprisoning Mirror doesn't negate continuous effects, I'm just not 100% positive which of these monster effects is continuous:

Reptilianne Naga

This card cannot be destroyed by battle. Continuous

The ATK of any monster that battles this card becomes 0 at the end of that Battle Phase. Trigger?

During your End Phase, change this face-up Defense Position card on the field to face-up Attack Position. Trigger

Spirit Reaper

This card cannot be destroyed by battle. Continuous

Destroy this card when it is targeted by the effect of a Spell, Trap, or Effect Monster. Trigger?

If this card successfully attacks directly, your opponent randomly discards 1 card. Trigger

Thanks in advance for any help. 24.210.251.140 (talk) 19:41, December 20, 2010 (UTC)
