Illaoi, the Kraken Priestess

At the beginning of your upkeep you may pay
{x}{x} if you do create X Tentacle creature tokens.
Whenever Illaoi deals combat damage each
Tentacle creature you control deals damage to
that source.
Sacrifice X Tentacle creatures: Search your
library and or graveyard for a Kraken card and
put it into play. Then shuffle your library.
