- 4 November 2015The tokens aren't named Elemental. They are named only Lightning Rager. The rule that says a token's name is its creature types applies only if the tokens aren't given a name by the effect that creates them.
- 4 November 2015If Rite of the Raging Storm leaves the battlefield before attackers are declared, creatures named Lightning Rager can attack you or planeswalkers you control.
