If it lives to your next upkeep it allows you to put any creature from a graveyard into play under your control as a Phyrexian
Not bad gains for an obscure 25-year-old enchantment
BUT WHEN, PRECISELY, MAY I CAST THIS
FYI: "Tournament-legal cards have a width x height measurement of 2.5x3.5, or 63.588.9mm. When it comes to the thickness, non-foil cards are about 0.012, or 0.305mm, thick. Foil cards, on their end, are a bit thicker as they have an extra layer on top of the card that creates that shiny, holographic look. When it comes to the corners of Magic cards, theyre rounded at a radius of about 0.125, or 3mm."
A notable exception to this rule is phrasing in the form of "[permanents/cards/other group] named [card name]," which continue to refer only to the specific name the phrase identifies, regardless of the card's current name
I dont want this as an EDH general and Tiny Leaders isnt an actual thing so I wouldnt worry about that propping this up
