Strategic players can find Atraxa a hassle to use, especially if they dont have the cards to make a deck that works around these disadvantages
You can do the typical Eldrazi thing, of course, as cascade preserves those precious cast triggers on Eldrazi, but theres also something to be said for the big artifacts package, especially with the insanity of Excalibur, Sword of Eden
Its hard to imagine Wizards ever printing a more perfect Aristocrats Commander than this
With its power doubled up, it will deal excess damage to a creature if blocked
Youre still able to play the best mana rocks and permanents with X in their mana cost (as X=0 when in the deck)
It has the perfect mixture of powerful interaction, ways to get ahead, and enough combo potential that Im always a little bit scared of what its going to do next
