what happens if your card got to golden in hearthstones battlegrounds

When a card becomes golden in Hearthstone Battlegrounds, it is usually a cosmetic upgrade: the card gets a golden frame and special animation, but its gameplay stats and effects stay the same. In Battlegrounds, the practical difference people usually care about is whether a minion is golden, because a golden minion gives an upgraded version of that minion’s effect and generally counts as a stronger copy.

What “golden” means

• For normal Hearthstone cards, golden is mostly visual.

• In Battlegrounds, a golden minion is the enhanced version created by combining three copies of the same minion.

• Some Battlegrounds mechanics can interact with golden minions in special ways, but the basic idea is: same card, upgraded version.

In plain terms

If you mean “my card turned golden,” then nothing bad happens to it. It does not lose value or stop working; in Battlegrounds, it usually becomes better because the golden version is the upgraded form.

One detail to know

A golden card/minion is not the same thing as “gold” currency in Battlegrounds. Gold is the resource you spend in Bob’s Tavern, while golden is the upgraded card state.

TL;DR: a golden Battlegrounds minion is the upgraded version of that minion, and a golden Hearthstone card is usually just a cosmetic variant with no gameplay change outside Battlegrounds-specific upgrading rules.
