So I was playing Leela yesterday vs NEH, and I'm trying out Muertos Gang Member. It has nice synergy with her ability, because derezzed cards are bounce-able, but rezzed cards aren't. It's also nice to get one run in, so with a field of unrezzed ICE, you make a run, they flip the ice, you play MGM, and now they're back to 100% derezzed.
In addition, they stack up. And the rezzing ability isn't even that bad. Case in point: my opponent and I were both at game point. I had three gang members in play. They IAA something in a two-ice deep remote. I had two out of my three breakers. I trashed all three members, and they rezzed both their ICE. The draws drew me into a Special Order, and I was able to see exactly what ICE were there, so I fetched my third breaker (which I needed, as it turns out) and managed to get in. Without the draw + knowledge, it wouldn't have happened.
It's possible I just hit a number of upsides with little downsides in these first few games, but it felt good.
