Elder Serpent Totem

First Strike
At the beginning of your upkeep, randomly
choose a creature you control and Serpent Totem
becomes a aura attached to that creature except it
has this ability. It also gains roll d4; that creature
gains +X/+0 (X = d4 results) and First Strike.
If you lose control of enchanted creature or it
dies then return Serpent Totem to the battlefield
under your control and it gains haste.
