Or do the cards produce infinite of the brown and grey resources now?
No, that would be insane, because a single card would cover the building cost of any other card.
With Tile 20 in play, each single, raw material (brown) resource card produces an unlimited supply of that specific resource.
To be thorough, with Tile 20 in play:
- Lumber Yards, produce an unlimited supply of wood.
- Stone Pits, produce an unlimited supply of stone.
- Clay Pools, produce an unlimited supply of clay.
- Ore Veins, produce an unlimited supply of ore.
Nothing more. Nothing less.
