Act of Treason Discussion

Pheardemons on Space Chicken DNA

I like it. If you want to go true "steal your stuff" I would suggest finding a way to add in stuff like Praetor's Grasp, Bribery, Acquire, Treachery, Mind Control, Control Magic, Domestication, Corrupted Conscience, and Fool's Demise. Before I made my grixis deck I was going to go Grixis steal your stuff so I do have some thoughts. Plus cards like Act of Treason which you can attack with thier creature, then sacrifice them to Ashnod's Altar which could trigger Dictate of Erebos (or Grave Pact).

Any reason Nicol Bolas, Planeswalker isn't in here? All Grixis decks can use him haha.

So I've had a look through and I've committed to the following;
Ogre Marauder
Thoughtpicker Witch
Traitorous Blood
Bone Splinters

I am going to have a look through and get rid of some of the higher powered cards, the demons, legendary creatures etc and hopefully that'll make it better to play.I already have Act of Treason so i'll put those in too which should help with the destroying of creatures

You're thinking of Cytoplast Manipulator, she is a beast aha. I have a Marchesa deck also and I just run all of the red steal creature spells like Act of Treason, swing in to get a counter on them then you sad them to something like ashnod's alter and because of Marchesa ability you get to keep them forever haha.

There are a few cards that do the same as Act of Treason, but just a little better, for the same converted mana cost. Examples: Harness by Force, Hijack, Kari Zev's Expertise, Traitorous Blood. Just some food for thought.

Love the idea! I'd add Goblin Bombardment and maybe a Mimic Vat if that interests you as a pseudo-Feldon.

You know another fun trick? Bazaar Trader. Target 'player' (including you) gains control (permanently) of a creature, artifact, or land that you are in control of (at least until end of turn). Basically Bazaar Trader is worded in such a way that you can keep the things you borrow. Act of Treason to take their creature until end of turn, use Bazaar Trader to give permanent control to yourself of the creature you now only temporarily control, and the new control effect overrides Act of Treason's temporary control effect so that you don't lose control of it at end of turn. Bazaar Trader on board literally turns our Act of Treason-like effects into Control Magic, only without needing the enchantment.

BlueScope on Act of Teason return to ...

It returns to the control of the player with the most recent control-changing effect in place, or it's owner if there isn't any. There is actually no technical difference between auras like Mind Control and other control-changing effects, as the aura's effect doesn't "overwrite" anything (or otherwise, you wouldn't be able to steal it with Act of Treason in the first place). The only difference is that the control-changing effect doesn't last until end of turn, but only as long as the aura remains attached.

To give an example:

  • player B casts Bribery, pulling any random creature from player A's deck. This control-changing effect lasts indefinitely.
  • on player C's turn, they cast Mind Control on that creature, taking control over it. Bribery's control-changing effect is still in place, but overwritten by the more recent Mind Control effect.
  • on player D's turn, they cast Act of Treason on the same creature. Again, both previous control-changing effects are in place, yet Act is the most recent, so it takes precedence. In the cleanup step, control of the creature returns to player C (who's Mind Control is now the most recent active control-changing effect).
  • On player A's turn, they activate Homeward Path's second ability, creating a control-changing effect for all creatures, which also lasts indefinitely and is most recent, so even though Mind Control remains attached, it doesn't do a whole lot at this point.

sges on Act of Teason return to ...

When Act of Treason or similarly worded cards effect ends at end of turn does the creature return to its owners or previous controllers control? This comes into play if a card was stolen permanently earlier in the game and you target it with Act of Treason. This does not effect creatures with enchantments like Mind Control or Hypnotic Siren as clearly the controller of the enchantment would regain control.
