Have you ever swung with a (2,765,958,938,624 / 2,765,958,938,624)
{heroe's bane}?  THIS GUY HAS!

I was Playing commander against {Roon of the hidden realm} with my {Azusa, lost but seeking} deck. I had just {terastodon}'d a few of his lands, so he had 3 elephants and Roon untapped. I had {vorinclex, voice of hunger} out, so all his lands were tapped (he couldn't activate roon's ability). I had out 39 forests, {sayasa's essence}, {heroes bane} (currently a 128/128), and {pathbreaker Wurm} (soulbound to the bane). I tap all but one forests for 1580 green mana, and double bane's 1/1 counters 395 times and swing for game!

Probably just turn it around with {Deflecting Palm} from KTK.
