Seldo, the Shocking Light

Whenever Seldo becomes the target of a blue
spell or ability, sacrifice him.
{3}{r}: Seldo and up to one target artifact creature
get +2/+0 and gain trample until end of turn.
Activate this ability only if Seldo is untapped.
{1}{r}, {t}: Seldo deals 2 damage to target creature.
At the beginning of the next end step, he phases
out.
