Phyrexian Juggernaut puts an 5/5 infect body on the board for five mana — that's ten poison counters of pressure split across two hits, or one hit plus any other source. The catch is mandatory attack and the must-attack-each-combat clause, which matters less in dedicated infect shells like Skithiryx, the Blight Dragon where you want it swinging every turn anyway.

Skithiryx, the Blight Dragon
Skithiryx, the Blight Dragon decks are built to stack infect threats and close games fast, and Phyrexian Juggernaut fits directly into that plan as a redundant five-mana infect attacker that doesn't need any setup to threaten a player's poison count.

Phyrexian Juggernaut is legal in Commander, Legacy, Modern, Vintage, and Oathbreaker, but competitive Constructed play isn't its home — Modern and Legacy infect decks run lean and fast, and a five-mana creature is simply too slow to matter before the game ends. In Commander, the card earns its slot only in dedicated infect strategies where the mandatory-attack clause is a feature rather than a liability. Outside of infect, a vanilla 5/5 for five with a drawback has no competitive home.
