The "Venom" monster part is really limited if you do not want to work with "Venom" counters, so aside from three copies of "Venom Cobra" to summon via "Rescue Rabbit", three copies of "Vennominon the King of Poisonous Snakes" as a recurring monster and potential beatstick and one copy of "Vennominaga the Deity of Poisonous Snakes" as the card with the alternate win condition, there is not that much that I would deem playable in the monster department
Skeletons have been getting a lot of support recently, so the best ones tend to be pretty recent

-Now goes to check Bulbapedia to see if Im wrong- On a different note, I always used to think it was a shame that they changed the colour palette of unlimited print run cards because they just dont look as visually appealing to me, but now Im glad they did, because if they hadnt, we would be missing that extra layer of history / transition and maintains something being special about 1st Ed and shadowless
