Instead, you unlock cards in game and 'extra' copies of cards are converted into Credits, one of the game's three currencies, that can be redeemed for single cards to add to your collection
After you've redeemed 400 codes, you will receive either crystals or coins
Together these cards are effective, but they also serve as a cumulative edge both against other Grixis-type control decks and Jund
The best part about this spell is its a quick effect, which means you can use it in response to (1) your opponent targeting a Vyon, Stratos, or Faris with imperm, (2) in response to Maxx C, (3) at the end of your opponents turn, or (4) during your own battle phase to push for lethal (example being you swing in for 1000 with Shadow Mist, pop mask change, make Dark Law, Shadow mist puts Honest Neos in your hand, swing for another 2400 + 2500)
Let's use Heliod, God of the Sun as an example
