Card protection is a layered system, and most players only run the first two layers.

Layer one is the sleeve - inner sleeve, outer sleeve, maybe a perfect fit. Layer two is storage: binders, deck boxes, cases. Both protect the card from handling. Neither protects the card in play, which is where it spends its most dangerous hours.

In play, the threats are environmental. Liquid is the famous one - a single knocked glass can hit a four-figure board state - but it is not the only one. Bare wood and glass tables grind at sleeve edges. Textured tables shed fibers into sleeves. Direct sunlight fades foils in a matter of seasons. Food oils transfer from the surface to sleeves to cards.

Spill-proofing by discipline ("drinks on the side table!") fails because it depends on every guest, every time. Spill-proofing by structure works: a play surface recessed below a hardwood rail means anything that tips over on the rail - where the drinks live, ideally in cup holders - stays off the field entirely. It is the same logic as a bathtub.

The surface itself matters more than most players realize. A dedicated playing surface should be smooth enough for sleeves to slide, matte enough not to slide on its own, and cleanable. This is what game-specific inlays are: a controlled, replaceable environment for the most valuable objects in the room. If an inlay ever takes damage, it swaps out - the table underneath never took the hit.

Sunlight is the quiet one. If your game room has strong windows, position the table so the field is out of direct afternoon sun, or run blinds during long sessions. Foils will thank you in five years.
