For that guy up above me. I'm betting that it works like N-gatcha. WC-1 of the corresponding rarity. You think they are going to put ex wild in any gatcha's? Hardly, they don't make money that way. plus if you get maxed on those cards you get ex levels anyway (to your limit). Also if you get there it means you play too much, or spend lot! LoL. when you get to that point let us know okay? as a free player I expect to get there sometime in 2020.
