mtg mirrodin cards Scars of Booster Pack put them into your hand Magic The Gathering - MTG:

With their partner in crime Tymna the Weaver (who we'll see in a bit) Thrasios is at the very top of the cEDH power scale, providing card draw and land ramp from the command zone, and game-ending combos on the battlefield

Another important point why Atraxa is "only" rated as a high power commander, is because in her commander identity you have already the top partner pairing of TnT = Thrasios, Triton Hero + Tymna the Weaver

I'm inviting a lot of Vampires

It is only because blue has so many potent cards that do much the same sorts of thing as Mystic Confluence that keeps this lower in the top five
