Phyrexia: All Will Be One
42/100
Loses value in 2HG: poison / infect.
A 2HG team loses at 15 poison counters rather than 10, so infect clocks are slower than the raw numbers suggest.
Ratings start at a neutral 50 and are adjusted by rules derived from 2HG's structure — shared 60 life, shared turns, two opponents. They'll be recalibrated against real play rates once teams start submitting decklists.
Create a 3/3 green Phyrexian Beast creature token with toxic 1. (Players dealt combat damage by it also get a poison counter.)
Corrupted — As long as an opponent has three or more poison counters and this card is in your graveyard, it has flashback . (You may cast this card from your graveyard for its flashback cost. Then exile it.)
