Card Name: Nebula Blade
Once per Turn Action - [2 Resource]: Attack
If Nebula Blade hits, create a Runechant token. (It's an aura with "When you play an attack action card or attack with a weapon, destroy Runechant and deal 1 arcane damage to target opposing hero.")
If you have played a 'non-attack' action card this turn, Nebula Blade gains +3 [Power] until end of turn.
