Clumsy Steward and Nightmare Lord Xavius bug

The “discovered” card from Nightmare lord Xavius when used with a Clumsy Steward on the board makes the ‘discovered’ card, temporary.

Discovering a card does not = drawing a card.

NLX card text:
Battlecry: Discover a minion from your deck. Give it a dark gift.

(card discovered, a minion with reborn)

Clumsy Steward text
After ANY card is drawn, make it temporary.

If you discover it from your deck, I believe it does.

That seems to jive. It’s the copy part I’m missing from it, or just outright discovering a card that is generated and not from my deck.

Thanks.

discovering a card from your deck will make you draw it, whereas discovering a copy of a card from your deck, or discovering a card from another source than your deck will not
