Which version do you have?

To simply own Steel Overseer, buy the Standard version for $1. The $3 Standard version offers no tangible upgrade in playability or core item quality; the difference is purely in the specific promotional printing or packaging associated with that set. Buyers focused purely on collecting the cheapest version should choose the $1 Standard. Those prioritizing the specific Core Set 2020 Promo designation should pay the extra $2 for the $3 Standard.
