Sent a Reward through the site, so it should be in your account under "Rewards". Let me know if it doesn't work (first time using it). Basically you had 20 decks donated so timed that equaled 100 random cards, 40 choice cards (from decks non-donated) and 40 choice cards (from your donated, limit 2 per deck).

The Randomizer has a "Donated" section at the bottom with 40 random cards if you prefer (or if it didn't show up) or if you want random choice cards.
