2 more upped quanta lets you Fractal twice in most games.
While I don't need to test since I've played this matchup hundreds of times when including testing, a bout in Trainer with Dragons over Psions and 2 more upped quanta had me go 1-9 as the Devtosis, and that's with AI Lobotomizing Burrow needlessly. Several games were lost to just one Fractal on Rays then Golden Dragon+Lobo beatdown. Even if I draw Steal to slow the bleeding, the chance to draw a second Bond that will heal a lot before death from Dragons and the early damage is slim at best. Had there been a Dusk and a 4th Bond (which is pretty common in Devtosis), the few 1 Fractal games could be won, but since most games had 2 go off, it's mostly moot.
It's really just the Psions and missed quanta ups. 12 quanta is more than I've ever needed to win most games against QC. 10 quanta used to be more common in the past, and that was enough to beat most QC decks too.
Obviously you weren't expecting QC though.
