Your favorite Rakdos Group-Slug cards?

Hi! Bought the Endless Punishment precon, made quite a few tweaks, and ran it a few games over the weekend with [[Valgavoth, Harrower of Souls]] as the lead. Did lots of small incremental damage, felt nice, but it started to feel like of Valga wasn’t really the slugger himself - he was just a card-draw engine, with a big beater attached. Felt great, but not quite what I wanted (I think?). I did have a couple semi-combos to close out the game (Chandra’s Ignition and Blood Artist, for example), but the incremental burn is missing a notch or two.

So I’d love some card recommendations, particularly punisher-style effects. I already got in [[Scrawling Crawler]], [[Spellshock]], [[Painful Quandary]], gonna get in a [[Manabarbs]], etc. Past these, what are your favorite punisher cards?

And then the big question — if I wanted to switch to [[Lord of Pain]] (which I do, he’s soooo neat), I’m losing some massive card-draw. What are some synergistic card-draw options to pick up the slack? I’m totally out of my depth as far as both Slug AND Rakdos go, so I’m trying to not just pick staples-cuz-staple.
