Older cards not in MTG Arena with high converted mana costs were added to the pool of cards that the Momir emblem can pull from. The abilities all work (though some aren't useful in a Momir context).

This was done in order to get a higher diversity of cards at higher converted mana costs to make the format more in the spirit it was intended. Impervious Greatwurm being the only 10 and Zacama, Primal Calamity being one of only three 9s was not the play pattern desired for this event.

Have fun! #WotCStaff
