Do all spells target on resolution and make reflexive triggers, or only multi-target spells? Does this apply to champion abilities?

Ruling: Only specific spells have reflexive triggers - Icathian Rain, Falling Star, Dragon Rage, and Twisted Fate. Not all spells create reflexive triggers.

Nuances:

• Reflexive triggers are indicated by "Do this:" or similar wording in the card text
• This is not a general property of multi-target spells, but specific to certain cards
