More "They didn't get to keep it because the DM went out of his way to make it painful to keep".
I wouldn't say the DM went "out of the way" to make keep ownership "painful"... Keep upkeep would reasonably be too expensive for a 4th-lvl PC... Check out DMG2 and Stronghold Builder's Guidebook... Also, if you're an adventuring party out adventuring, who's gonna watch the keep? Do you think it will just go unnoticed??
Anyway, oftentimes the Deck of Many Things is a bad idea, ESPECIALLY for lower-level parties. Just simply too powerful. Either reserve the thing for higher level or alternatively if you as a DM or player like the "cool randomness factor" maybe design a deck with effects that are not so powerful...
Another problem is that many of the cards are extremely vague, including the "balance" card, "fates" card, and the "throne" card (which uses both "keep" and "castle" in it's description, not necessarily synonomous terms in my opinion). Maybe house-ruling details before the item is introduced would be a good idea, that way DM arbitrariness/revenge/punishment would be avoided...
Also, I believe that you can only draw one card at a time, one per round, so the "poker" idea wouldn't really work...
