Should all justice cards be worded like this or similar? Otherwise we can't have +X/+X or adding keyword bonuses.

I think so.

I think there is a slight confusion if the law has the "last turn" text. I think we are going to need to have access to these keyword bonuses particularly for commons.

Can you define the leading option for justice?

New wording means this card works a lot better

So wait, given the confusion over Mindleak Agent's template, I'm now genuinely unsure - was this meant to punish people for targeting their own creatures (ones that you-the-Patrol-Thopter-controller don't control), or punish people for targeting anyone else's creatures (ones that you-the-player-whose-turn-it-is don't control)?

the second option.

I'm not sure if you guys care or not, but this is one weak creature. I would think a +3/+3 bonus is well warranted. Or, alternatively, let the card be a multiplayer slugger and allow this creature to say "for each opponent who broke the law"...

Artifact flyers are in a weird place anyway. A 2/2 flyer is playable even at 4 mana or more, but a 1/1 flyer doesn't do very much. This could be 2 mana or +3/+3, true.

Do note though that this has the snowball effect with all other Justice cards you get onto the table. If you have Protector of Spirit and Suppressing Agent as well as this on the table, then all of them will trigger their Justice abilities when any of the laws get broken, and the opponent starts finding their options rather tied.

Ah. It did not occur to me that this is a linear mechanic. Well, that's unfortunate. I'm not a fan of mechanics that get worse outside of block.

jmgariepy each card still works by itself, just not as well. Similar to Rally.

Yeah, each card does something on its own. This one is less interesting than most, just being a 3/3 flyer; but even that could have the interesting effect of making opponents second-guess whether they really want to Shock your utility creature.

Almost every mechanic is worse outside of block. That's because blocks are deliberately designed to have lots of support cards for all their mechanics.

Now if you're saying you don't like parasitic mechanics, yeah, that's fair enough. Each Justice card works on its own, but in the same way that Kor Bladewhirl or Fury Sliver work as standalone creatures; they do leave you itching to draw something that ties in with their ability.

But having been looking at it for a number of months I think there's quite a fair amount of design space in Justice effects. The first Slivers were very parasitic; the next time Slivers were printed they were somewhat less so; now if Slivers come back they're heralded as a cool throwback that provides additions to a bunch of casual decks. I think Justice has potential to be a mechanic like that.

Can you give a reason for removing this? Did we decide on no artifact justice?

Yes, we don't have room at common.
