I'd say the number of games like that is not few. 10k in equipment in most sports will give you an advantage over 1k in equipment.
It's more accurate to say that the entry cost into the Vintage format is 10k (or whatever the cost of the deck you want to play). You can't just throw money at the deck and increase its winrate unless your deck starts out suboptimal.
