Act of Treason Discussion

rdean14 on Card creation challenge

1 day ago

Angrath's main power is the ability to gain control of creatures, like Act of Treason style.

My favorites are Aminatou, the Fateshifter and Kambal, Consul of Allocation.

a Pre-Spark version:

Aminatou, Eldritch Evangel

Legendary Creature - Human Cleric


Whenever another nontoken creature you control dies, scry 1 and create a tapped 1/1 white Spirit Insect with flying.

Creatures you control but don't own have lifelink and protection from their owner.

, , Target opponent gains control of another target creature you control: Gain control of target creature that opponent controls with a lower converted mana cost than the creature they gained control of this way.


This represents her nascent foresight abilities, and instead of being able to really conjure them unaided, she requires sacrifices. Also her ability to alter fates is based around exchange of fates than a more pure manipulation.

Same challenge, make a favorite commander in a different situation.

Unlife on What was your favorite play ...

My friend is playing Karametra, God of Harvests, I'm messing around with a Nicol Bolas Act of Treason deck.

They play creatures, I steal them and swing them back, should be fun, right?

Nope, mana screw hits hard. He's ramping and ramping and filling his board, and I've managed to drop a Goblin Bombardment. I eventually hit a Treacherous Urge for his Kozilek, Butcher of Truth, but I'm not doing well.

He's ramped enough now to throw down Storm Herd.

Hey, I get to do something. Reverberate.

Now we both got an army of 1/1 fly pegasus but he's got the advatage still. Hmmm...

Oh, right. I've got Goblin Bombardment.

I manage to win the game by throwing all my pegasus at his face.

Omniscience_is_life on What was your favorite play ...

5 days ago

that was quite a tale, I don't know if mine will be recounted near as eloquently, but here it is:

I was playing my Atla Palani, Nest Tender deck, and I had been lucky earlier in the game and hit a turn 6 Zacama, Primal Calamity. Now, I'd been swinging with her for a few turns since then, but she was my only threat. The two other players at the table had been eliminated, however (it was down to me and a Krenko, Mob Boss deck), so I felt a little less happy about how small my board was. Nevertheless, I began the tedious task of attacking through the 15 or so goblin tokens on my opponents' board. Then he played an Act of Treason, and hits me with my own Zacama. I'm like "ok, no big deal, I'll just ping his tokens for a turn until I can attack with Zacama again...", so I do so and pass. Then he Kari Zev's Expertise's, and hits me again with my own Zacama! I at this point am a little worried. Suffice it to say, I still won the game, but my opponent ended up attacking me FOUR TIMES with my own hard-hitter, don't ask me why he had so many Act-type effects in his Krenko deck :/

TriusMalarky on What are equipments with downsides?

1 week ago

Can I also point out that Magnetic Theft and Act of Treason effects are the only ways to get these attached to our opponent's creatures? The Equip ability literally says 'Attach to target creature you control'. That means, no other creatures. Meaning that you have to have these other cards in hand to be able to use your bad equipment in any way.

Don't use equipment as removal. You totally could, however, build a deck around equipping your creatures and buffing them up a ton. There's enough support for that that you could build a fun and fairly decent(in casual games) deck. Might I point out Valduk, Keeper of the Flame and Kemba, Kha Regent?

SilentPlague on Black & Red Aggro

I see the control, but don't see much of the aggro. I don't necessarily see this being a win by turns 6-8. That is generally where I draw the line for aggro, but don't mistake me as the authority on that. Your deck average CMC is good for this, 3 or under in my opinion. Dreadhorde Butcher is a great early game play. I'd have 4 in this deck. Sprite Dragon is a good card, but not for this deck. You have at best, 6 chances for an island, given you are not short another color and that makes Sprite Dragon difficult to play early like you would want. Having either Nicol Bolas, the Arisen or Nicol Bolas, the Ravager  Flip for the late game is doable, but if you take out those 2 and the 2 faerie dragons, I think you can find better fits. For my agro decks, I assume if I can't win early, I likely will not win at all. So I have no back up. This lets me focus on putting in more aggressive creatures for the early game. You have only one other demon.

Also note that Avatar of Woe and Bone Dragon really work against each other. Maybe focus on one of them. For instance, you have cards for exiling creatures (not good for the avatar). So maybe Bone Dragon is the choice here. You would likely want to not have cards that pull spells from your graveyard as well. Such as Unbreakable Bond if you want to keep getting the dragon back out. Also note that Rakdos, the Showstopper could really hurt you in this scenario even more than your opponent. Not sure that card fits here.

I would suggest looking into cards with menace. They are usually cheap and are very aggressive, given they are hard to block. Stormfist Crusader is a good one that can work with control as well. To keep the control aspect, put in cards such as Heartless Act and Terminate. This keep the opponent creature count low and the game in your hands. Act of Treason is a good one to keep in for control.

Sorry if I went too deep here. You can ignore me and it won't hurt my feelings. I'm just snooping around getting ideas of my own as well and waiting for criticism to come back to me from time to time.

Omniscience_is_life on Assist Question

2 weeks ago

Interesting question.

I think (credit due to Raging_Squiggle for beating me to it) that since the text of the Assist mechanic is “another player”, it isn’t limited to 3+ player games.

I’d be interested to hear why your opponent would help cast a card for you, though. Fodder for an Act of Treason??

psionictemplar on Gruul Elfball

Thanks for the upvote on my emry deck.

After looking at your list, I think you don't want Storm's Wrath in here. It would kill all your creatures being the reason why. If a larger creature is what is in your way, then you would be better off just stealing it with something like Act of Treason and continuing to attack. If planeswalkers are the bigger concern, then main your The Immortal Sun and cut your walkers out. At the very least switch them to ones that have a base effect even without their loyalty abilities.

These are my base thoughts, but take them with a grain of salt since I don't really play pioneer.
