Splicer Vandal

When Splicer Vandal enters the battlefield, you
may sacrifice an artifact with mana value 3 or
less. If you do, search your library for an artifact
card with mana value equal to or less than the
sacrificed artifact's and exile it. Then shuffle.
{r}, {t}: Create a token that is a copy of the exiled artifact. Exile it at the beginning of your next
end step.
