This card is great for two main reasons:
- it let you check R&D and avoid all the nasty traps that could hide there
- it gives you knowledge about what will be the next five cards drawn by corporation
In most cases, you will want to play it on your first click, to have enough time to come back for any agendas you moved up front. Be careful about Jackson Howard, because his deck-shuffling mambo jumbo can negate effect of this card. But on the other hand, you can use Indexing to lure corporation into wasting Howard sooner that they would want. If you play it, be sure your run will be successful and you will be able to use it, it would be a shame to lose it's powerful effect to Caprice Nisei or Crisium Grid.
If there are no agendas in five cards in R&D, you will at least now know to look for them elsewhere.
With 3 influence cost it's not something you can fit in any deck, but one copy here and there in Criminal or Anarch deck can be very surprising for the corporation. In the way they won't really appreciate the surprise. It's event, so after Comet lands, there will be some pretty nasty combos to play with The Maker's Eye.
