Is it even right to play a KotR+ Retreat "combo" like it's always supposed to be a 20/20 Knight you're trying to make, though -- like, this is Bant we're talking about, board control is second-nature here, there are probably times more often than not where you'd just play the Knight like it was a Phyrexian Processor or something, and just make it a 10/10 unless you actually had to go huge. That shouldn't dick with your target land base too badly, right?

Retreat seems like one of those cards that would be a pretty good enabler type thing in a deck where you can just make it do more good things more often, though I guess that's the embodiment of a "win-more" card isn't it. Hmm
