Whenever you cast a Phyrexian spell, each Eldrazi you control gets a oil counter. Also each Phyrexian you control counts as an Eldrazi, and vice versa.

Remove any number of oil counters from among permanents you control: gain control of target non-token creature with mana value equal to or lesser than the number of counters removed, that creature is a Phyrexian Eldrazi in addition to its other types.
