Act of Treason


Gain control of target creature until end of turn. Untap that creature. It gains haste until end of turn. (It can attack and this turn.)

Sacrificial Lamb


As an additional cost to cast this spell, sacrifice a legendary creature.

Draw two cards.

Would be great in Commander if you can nab someone else's such as with an Act of Treason or if someone enchants your creature with like a Darksteel Mutation or something

Wow, this is a really cool deck! It certainly looks like fun abusing Actual Literal Biblical Satan.

I have one small suggestion. Hell's Caretaker doesn't really work here, as you can only use it on your upkeep. This means that Act of Treason effects don't let you sacrifice the creatures you steal to the Caretaker. I'd recommend cutting it for one of the following: Altar of Dementia, Woe Strider, or Viscera Seer. All of these are free sac outlets you can use whenever.

Again, I love the deck! I have a similar deck that I play a lot, Memnarch's Eleven. It's a similar theme but mono-U instead of rakdos. I'd love it if you could check it out and maybe make a few suggestions. Thanks so much!

plakjekaas on Would Seedborn Muse Be Blue …

Untapping creatures is a very red thing to do as well, for extra combat phases and Act of Treason effects. I agree that would look weird on Seedborn Muse, but I think it's not right to say green focuses most on untapping creatures, since it's Seedborn Muse that makes people think that. If it was printed as blue the first time, we might be thinking of blue as the most untapping color.

But the best reason to say it might be blue, is because you're effectively taking the resources of an additional turn during each other player's turn. Extra turns are almost exclusively blue (save maybe the red ones that make you lose the game at the end of that turn). The only extra turn green can take is Seedtime, and that's even dependant on blue spells being cast. I suppose that makes the most sense to me for thinking Seedborn Muse should be blue.

The Muses were a cycle though, if Seedborn should be blue, what of Dreamborn Muse? That card is a lot more blue than green, in de X-born Muse cycle, Seedborn makes the most sense in green.

Aggravated Assault Breath of Fury and Seize the Day were all on my radar, I was going to play it a bit and see what cards just didnt feel right and trying some extra combat effects were at the top of my list.

I feel like had enough theft effects and just I kind of threw Act of Treason in or similarly Eternal Witness kinda got thrown even though I feel pretty comfortable with the amount of recursion I added like Tenacious Underdog(I didnt realize I like in the Deck so much because it can sac itself so maybe I should look into that) or Endless Cockroaches.

I just really wanted to something aristocrats but I feel like I could used any commander and use the aristocrat staples so I started leaning into the theft effects now I’m just worried I’m spread a little too much between the 2.

What mana dorks are there? Like Sakura-Tribe Elder & Birds of Paradise

What are you thinking you would remove?

Falcata on Doubt about sacrificing Seed Guardian …

Hi, I have a doubt.

If my opponent takes control of Seed Guardian with Act of Treason and then sacrifices it with Altar's Reap, would the x/x token be created in my opponent's zone or in mine?

Thanks in advance. We have argued endlessly and tried to find the answer in the official rules, but we can't find the answer, we need a lawyer xD

Neotrup on Can i take permanently control …

No. Act of Treason creates a control changing effect with a limited duration. It never "gives back" the creature, the effect simply expires. In addition, protection granted by Gods Willing prevents Damage, Equipping/Enchanting, Blocking, and Targeting. It can stop Act of Treason from resolving by making the targeting illegal, but once the spell resolves it no longer targets and the control changing effect can't be interacted with other than creating a new effect that overwrites it (such as by another player casting Ray of Command or activating Homeward Path).

calvo099 on Can i take permanently control …

Suppouse i use Act of Treason and i take control of my enemy's creature, then i end up my turn and when Act of Treason's forces me to give back the creature, cast Gods Willing and give protection against red to that creature, do the protection against red disables the "give back" ability from act of treason? if thats the case, would i keep that creature?
