It was 3 golden Wrath Weaver and hero just some casual, nothing with card ability
Wrath Weaver is TT1, so most common. If said player stayed on low tiers and kept rerolling, it's possible. Some other heroes are also helping with rerolling like Nozdormu or Malygos or Arana with a bigger selection.
It also depends on what other players were playing and whether they were contesting the same cards or not.
