Remus, Aetherial Conduit

Whenever Remus, Aetherial Conduit attacks or enters the battlefield, create two 1/1 white and green lightning elemental creature tokens with: "Whenever this creature attacks, deal 2 damage to target creature or planeswalker".

If you own and control a Legendary Creature named Lucy, Awakened Storm and five Lightning Elemental creature tokens, exile those tokens and Lucy, then return Lucy to the battlefield transformed.
