He is somewhat exaggerating, as most of the MOST espensive cEDH decks peak at around 10k, which is frankly a TON of money but comes from 2 or 3 cards. Take Urza for example: the best Urza Poly Kraken deck (uninterruptable combo deck reliably wins turn 3) is like 9k because it has timetwister, tabernacle, and mox diamond, among other $200+ pieces. This deck is a solid 7 cEDH deck, which places it among the best decks ever. However, drop it to a cEDH 5 and the price drops to 2k because you can cut those crazy cards and make other subs. Drop it to a solid budget cEDH deck and you can get it to $500. Each extra insane piece adds only a nominal amount of power.
