Rafiq of the Many and The Ur-Dragon combo off to insta-kill an opponent
Serendib Efreet's artwork was fixed, but the artist's name wasn't updated (same for Plateau, which also didn't include the correct artist credit)
Bone Miser is a creature with an identical effect to Waste Not
There are also lots of effects that we don't allow at common, such as tutoring, reanimation, permanent control change, spell copying, etc
We'll get the Vehicle sub-type much later, and Equipment basically streamlines a lot of the messiness and (in retrospect) poor mechanical flavour of a lot of these earlier artifacts, but it's interesting to see the roots of those newer mechanics in these earlier sets
However, we chose all of our cards with these matchups in mind, and fought to a point where we werent afraid to be paired against any of them
