There were just so many Phyrexian creatures in All Will Be One that having a card that cared about them felt almost too easy, at least in the context of sealed and draft where over 90% of the creatures had that creature type

Imagine countering your opponents spell with a Flip the Switch, then buying it back the following turn with a Repository Skaab now thats value
A bit slow, unsurprisingly
