Any one using House ad to show HTML page (content) as ad

Hello All,
I use to have custom house ad under old admob displaying my own HTML page (HTML content)
But new admob is not allowing me to create HTML house ad (it only allows for image or text)

Any one is using House ad with own HTML , may be with another ad network that support house ad.

Or May you help me to create list of ad networks that allow house ads?

Thank you,
