Sorry for the delay in replying.
The alpha boosters are now sold out. The only way to get them is on the secondary market which is available after you buy a starter deck, through referral bonuses, or in the eventual (very limited) wax sale in the future.
To get one of the starters and gain access, you can follow my referral link in the post. Once you get to the exode site if you click where it says "game status early alpha" it will bring up the shop interface.
Using a referral link to buy a starter gets you two account bound alpha boosters
Hope that helps. Sorry if I'm unclear, I'm on my cell phone.
