on the overpowered discussion:

Imagine 3 sides starting the game:

1st with dish: popping free archons, unlimited communication/intel
2nd with hammer: popping free dwagons, combat moves (flight, lightning)
3rd with pliers: decrypting, dust uncroaked

Which side would you like to play?

All artifacts are possibly "gamebreaking", which means that the side controlling them has a huge advantage. Which one is "better" depends on the situation. At the moment the circumstances favor the pliers but don't forget that the circumstances are what a gamer dreams to pull off: lure a major force into a trap and turn it against your opponent by some means (decrypt/bribe/mind control/misdirect/...). Things like that don't happen a lot.
