The name sounds like an artifact - considering the theme of the set and that you have tap-down Gadget as an option you probably want cardnames to strongly indicate whether they are artifacts/artifact-themed or not.
Simplest fix would be "Means of Distraction" over "Tools of Distraction".
This is a color pie bend more than a break as Gadgets are colorless and colorless already has access to tapping creatures, making mana, looting, and +1/+1 counters.
In general, I expect Vryn to be Blue-Black tinged in a way that is similar to how Scars of Mirrodin was Black tinged. I'm trying to use espionage as a theme for a set which is traditionally very blue black. There is going to be quite a bit of flavor bleed and hopefully only some minor mechanical bends.
Ugh, still seems pretty rough to me. Putting that aside for a second, isn't it highly questionable for the color pie that every color that provides gadgets can loot, tap creatures, and do colorless rituals? All of those are pretty okay for to do (though colorless ramp without any restrictions is more on the questionable side) but looting and colorless ritual-ing isn't really.
I've removed the gadget creature and come up with a partial sollution to the gadget token distribution problem. I've created a 4 way split card with all Gadget tokens printed on it. All tokens in this set will be double sided with one sided having this 4 way split card. In this way, I guarantee that every 'pack' has the tools needed to understand and use each card. A mock up of the 4 way token is linked below.
Exploit variant of Assassinate. Flavor based on the idea of "lost" assassination attempts where in the assassin dies as part of the assassination attempt.

Total redesign

Cool, I recall a card I made once was something like
>
Instant (U)
> Return target creature to its owner's hand, then exile it until end of turn. (It returns to that hand.)
Name and Flavor Text added
Name change: Lost Assassin -> Expendable Hitman
spelling
Flavor later

I remember the power level of the card being its principle problem. And also, its omnipresence due to company. I could be wrong though.
I've also made some changes to the template of the card to try to mitigate memory issues.
changed from reflector mage template to a new exile based template which hopefully reduces memory issues.
