Lovegood to disable The Source while still triggering a Steal for Aaron counters. Basically you choose between Film Critic or Lovegood depending on whether you need to Steal, or dodge On Access badness (like Fetal/Future Perfect).
ProCo by himself gives the deck enough draw, oddly. If I get Jak and John out together, that's almost enough draw, unless they ice up everything... Hoppers are very very rarely used for card draw, because the cost of installing them tends to negate the 3 cards you drew. (Unless you installed them off Supplier.)
So... Here's the thing, Sunny crushes every Corp in the Late Game. Every Corp crushes Sunny in the Early Game, though. Thus, we have two options: Accelerate Sunny's game, or Slow the Corp's game. The Source slows their game to a crawl, especially if they have to run through it multiple times via Fall Guy. I'm very much not on board the Peace In Our Time train, though, because while it gives Sunny a huge credit boost, it also speeds up the Corp which I'm not really ok with. Add in that it has an influence cost, and I'm out.
I've gone over multiple times why I dislike the OCA engine, and it's not for lack of trying.
I have been finding that Overmind gets stuck in my hand a bunch, but it's simultaneously very useful; once. I'm going to try cutting it entirely and going to 3x Daily Casts, and upping the number of Jak to 2. Bump John up to 2 as well and cut a Security Chip, since I only generally need one of those things a game. I'm also looking hard at Freedom Through Equality, since HB decks have sort of fallen off a bit I may not need to tech for them... Still, GFI is around, so I might keep it around a little longer.
