At the start of combat on your turn, you get to put +1/+1 counters on another creature you control equal to their power

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
These may include unique themes, shiny Pokmon, or exclusive cards
To actually win, it requires that you assemble multiple other pieces to generate excess mana and have a spell to play an infinite number of times
