Unlocking Wild Format and Wild Cards

Thanks to being cooped up due CV, I have been playing this addicting game. I have received cards and packs from challenges and I have bought card set from sets such as Witchwood and Boomsday which I understand will no longer be in standard effective 7 Apr 2020.

I am level 25 and Wild has not unlocked. I have played other formats and evidently I must not have any wild cards. When my cards from Witchwood and Boomsday are moved out of standard, will Wildwood finally unlock? Will I be able to use these Wildwood and Boomsday cards in wild?

I have researched this info, but I can’t find anything definitive. I really want to play Wild and have friends who play. I am still a noob, but I am enjoying the challenge of playing and getting better. I know I will get owned in Wild, but this is all for fun.
Thanks for any help. Hopefully this is the correct forum.
