Yeah, true. Esp with Witch/MBank.
But the thing is that whole game is pretty boring, linear and random. If he had drawn "Copper, Rebuild, Rebuild, Rebuild, Silver" (his last hand that he didn't get to use) a turn earlier, he would have won.
I mean, yeah, I'm a Spike, and it is obv winning stratagy and I'd go with it anyway, but GOD is it boring.
