Viserai // Crucible of Aetherweave [U-ARC076 // U-ARC115] Unlimited Normal

Whenever you play a Runeblade card, if you have played another 'non-attack' action card this turn, 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.")
