Maybe they should print a Comparative Strengths that actually does what the original card intended to do before hosing any effect at all...
[Insert Element that is Not Void Here]
Counter Permanent (2)
Turn 2 Hand cost 0
Target: 1 Ninja
Effect: Attach this Mission to the target. While this Mission is attached, the targets gains the following effect: "Valid: This Ninja cannot use Jutsu with 1 or more specific Symbols in its Jutsu cost."
Hoses Jutsu with specific users, but doesn't degrade the game into dedicating 3 slots to it because you can negate any effect too. I'm not gonna complain, but I didn't exactly find it very interesting to run a 44 card deck back in the day when it was x3 Tobi x3 Comp Strengths or Bust.
