Not a big fan of this. I would rather just have a sorcery that was cheaper and took anything. The main problem is that this costs so much you can't really hope to steal + exploit, which should at least be a possibility IMO.

We could reprint Act of treason or traitorous blood here. That would be safe. As a last ditch suggestion, what if we made the creature an artifact as a twist? will have the thopter generals doing artifact tribal, so this could give some random bonuses to a stolen creature.

Reforged
sorcery
Gain control of target creature until end of turn. Untap that creature. It gains haste and is an artifact in addition to its other types until end of turn.

Twobrid mana makes this card a massive trap for people who don't understand how CMC works. I feel like if we're going to do anything involving CMC-matters, it should be at least uncommon+ and they should focus on "Equal to the CMC" (eg. Æther Mutation) rather than "less than CMC" (eg. Horribly Awry) since "equal" works well with Twobrid and "less than" works worse with it.

Yeah, I didn't think about the CMC thing. Makes me like it even less.

What if it was just Threaten that could also take artifacts? Like a not useless Metallic Mastery?

­ steal a creature or artifact for the turn? That could work!

Guys this card is in a hybrid slot for a reason. If you're trying to not make it hybrid we need a hybrid replacement (and also to kick out another spell)

I think Act of Aggression is an excellent template for this card if we choose to keep it Twobrid. Something like:

Totally Not Act Of Treason
Instant [Common]
Gain control of target creature or artifact until end of turn. Untap that permanent. It gains haste until end of turn.

Edit: just realized this should probably be a sorcery, since most common AoT effects are sorceries to prevent you from using them defensively. Still might be interesting as is though so I'll leave it for now.

Sorry MOON-E, I forgot two-brid for a moment there :)

If we want it to be cheap to combo with exploit, it definitively needs to be a sorcery.

Totally not Act of Treason version 2.0
Sorcery
Gain control of target creature or artifact until end of turn. Untap that permanent. It gains haste until end of turn.

I'm not so sure 1RR is worth the extra addition to Act of Treason.

Could we make it into a one-card March of the Machine?

Karn's Touch
Sorcery
Gain control of target artifact until end of turn. If it isn't a creature, it becomes a creature with power and toughness equal to it's CMC until end of turn.

Totall not Act of Treason versin 2.0 looks solid. "Karn's Touch" is a good card but would be uncommon.

Agree that Karn's Touch is an uncommon, but I like it much more than TnAoTv2. It has mush more flavour and interesting gameplay. Would anyone be okay moving the Act of treason to uncommon as Karn's Touch? We would then need something else to fill this two-brid spell slot.

Do we have any theme in Red that requires another card in common? If so, we can push this as Karn's Touch at uncommon and use this slot for one of the themes. (This might have to become something like Dragon Fodder or Hordeling Outburst for Exploit to be happy)

Red is currently missing a little bit of personality. What we have right now can be split into Thopters, direct damage, and artifact hate. We could go for something creative and flavourful here, and bump Karn's touch to uncommon.
