Act of Treason Discussion

GhostChieftain on What Commander for Grixis Steal ...

I will also say marchesa. She can be pretty nutty, especially with things like Slave of Bolas and Spinal Embrace or even a simple Act of Treason + Viscera Seer .

If not marchesa, I would say vial smasher/kraum simply because they are very strong and not because of any synergy.

Marchesa, the Black Rose - Her ability enables permanent theft even out of temporary theft effects like Act of Treason or Sower of Temptation . If it has a +1+1 counter when it dies, it goes to its owner's grave til end of turn, then comes back permanently under your control.

Act of Treason 's role in the deck is to steal the big flashy win cons like Hydroid Krasis that the opponent plays. I'll take out 2 for 2 shocks, though. Torbran, Thane of Red Fell unfortunately does not increase the damage that Gingerbrute deals because Gingerbrute is colorless. This kind of defeats the whole purpose of the deck.

Not a fan of Act of Treason in the list. Maybe 2 Torbran, Thane of Red Fell and 2 more shock to finish the playset.

seshiro_of_the_orochi on Custom Commander with wording issues

Feather, the Redeemed gave Boros a whole new angle in Commander by making combat tricks a viable deck type. What if there were a commander that made a similar thing with Act of Treason type effects? I tried coming up with a card for this. So I present to you:

Feather, Eternal Recruiter

Legendary Creature - Zombie Angel


Whenever you cast an instant or sorcery spell that causes you to gain control of a creature you don't control, exile it instead of putting it into your graveyard as it resolves. If you do, return it to your hand at the beginning of the next end step.


So I see several issues with this card:

  • The wording is very obvious about what the card is meant to do. I generally don't like this very specific approach, but I don't know how to word it differently without making it too powerful. I thought about something like whenever you cast a spell that targets at least one creature you don't control, but this would just make spot removal the better choice for a deck around it.

  • It's a lot too similar to original Feather with both a mana cost shifted from Boros to Rakdos and the same stats and additional keywords.

What I like about the card is the flavour: What if Feather had fallen in War of the Spark and thus became an Eternal herself? She'd be the best recruiter the Dreadhorde could wish for.

My questions are:

  • Do you have ideas on how to word the ability less specific without making spot removal a more viable path than Act of Treason spells?

  • What would you do to have the card differ from original Feather a little more?

  • Do you like the general idea and flavour of the card or would you prefer another character to have this ability?

Thanks a lot for your answers.

In the pauper format you can have up to 5 uncommons in your deck. Maybe replace Opt with Sleight of Hand or Preordain . And maybe add Traitorous Blood in place of Act of Treason

I don't apear to have Lightning Bolt , is Shock and Lightning Strike decent replacements? For Act of Treason , should I replace it with Volley Veteran ?

I will replace 2 of the 4 Expedite cards with Trumpet Blast . The other 2 Act of Treasons, I might keep. I kind of like them in the deck.

Walking Corpse could be donned by the Shocks, and the Lightning Strikes can replace Corpseweft , Abnormal Endurance and a Dread Wanderer .

I will try and get some of those cards you recommended, like Goblin Bomb or Goblin Bushwhacker.

Thanks again Caerwyn
