Phylactery Gambler

Indestructible
As Phylactery Gambler enters the battlefield,
add the top card of your library to the ante.
When an opponent adds a card to the ante,
sacrifice Phylactery Gambler.
Daenerys does not want Hentai! but John Sand does
not agree. Collect chests filled with gold to make war
on him! And save Daenerys!
