Overloaded Circuit

Strategy

• More important than Knowledge Vault, but the same rule applies: don't go out of your way to fill it.
• If both players fill it on the same turn, both deal the 5 damage. Revealing first doesn't win the race.
• Racing to fill it tells your opponent where your cards are going. That's how a Little John gets his +2/+2.
• Weigh it against the other locations on the board. If Amplifying Amphitheatre is out, you don't send resources here instead of there.
• If filling it was already part of your game plan, go for it and deliver the 5 damage to your opponent's barrier. Otherwise play the better location.
