If you are going to run anything in place of wrath/humility, then run disk, contrary to common belief, it is pretty cool to sweep all the opposing crits/CBs/whatevers... and it is unstifleable (well, stifle doesn't stop it forever at least)...

I actually find the card very good in a stompy/threshold meta (kills all the other shit as well as the creatures) while still being able to play it/ use it when and if a bloodmoon is online...

Needless to say, if no humility, then disk, if you are running neither, then you are insane... or playing deed
