Lightning Construct

At the beginning of your upkeep, choose one: Lightning Construct deals 2 damage to target
creature or planeswalker; scry 2; or gain 2 life.
When Lightning Construct would be put into the graveyard from the battlefield, it deals 2 damage
to target creature or player, scry 2, and you gain 2
life. Then shuffle it into your library.
Arcturus' private bodyguards, they are as volatile as
the lightning elementals contained within them.
