Act of Treason Discussion

Grind on Brion Stoutarm

5 days ago

brion is great. cool deck and nice start.
if you want to leave in Academy Rector as a generally good card, you could just add more enchantments - Test of Endurance for a wincon or Oblivion Ring or Grasp of Fate for removal.
you could run Boros Signet over Fire Diamond.
also your Sunforger package looks a little lacking. you could consider Swords to Plowshares and/or Return to Dust. Warleader's Helix or Lightning Bolt can hit planeswalkers if need be.
i have a brion deck and found that instant speed Act of Treason effects are worth the extra mana. i run Act of Aggression and Turn Against - that way you can burn the card and use the ability when your opponent swings at you to save yourself some damage, too. it allows you to be a little more political.
also you can know that Phyrexian Devourer is a one-hit kill card (at a high cost to your library). he's my favorite finisher in a brion deck, and can be tutored up with things like Enlightened Tutor and Hoarding Dragon, both of which you're already running.
finally, if you ever feel like you're wanting for card advantage, Staff of Nin, Outpost Siege, and Crystal Ball are surprisingly playable.

Kari Zev's Expertise would also be a pretty great replacement for Act of Treason

AceGambitDragonfly: Thanks for your feedback. I only play Magic with a handful of friends at the kitchen table and we don't ever use sideboards. Infinite Obliteration is there because one guy keeps wrecking us with Reflector Mage and Emrakul, the Promised End so I'm hoping to snuff those out early if I get the chance. If I played in real tournaments, Infinite Obliteration would definitely be a sideboard card or not included at all.

Mark of Mutiny does look like a strictly better choice than Act of Treason for this deck since I'd be unlikely to take control of a creature if I didn't have an way to destroy it before the end of the turn. If the deck runs well I'll probably make the switch. As it is, it's built entirely of cards I already owned which is why there's a lot of 1 ofs.

I dig the deck style, this seems like a lot of fun. Infinite Obliteration seems a little out of place here though, like maybe a sideboard card? Is there a specific use case you had for that card?

Sepaerately I'm wondering if because the creatures are going to die before the end of turn, you might get more mileage out of Mark of Mutiny instead of Act of Treason.

Final note: Blood Artist/Falkenrath Noble would do wonderful things in this deck.

Well after using Act of Treason, you just use Cloudshift to take control of that creature permanently. Then you can sacrifice it using Butcher of the Horde or Bone Splinters if you need to. Otherwise you just keep it forever. #Kidnapped

There is a little stack of cards in this deck that I would most certainly cut;

First, the creature-takeover cards. They seem pretty good, but you must make sure to focus on one thing. So Ray of Command, Act of Treason and others.

Second, the other cards that take over your opponent's cards:Confiscate, Charisma, Annex.

Also I'm not a fan of the Equipments and any of the creature-based cards in this deck, as the Izzet guild's strongest point is spells.So cut Teleportal, Assault Strobe, Psychotic Fury, Fury Charm, Curiosity, Pemmin's Aura, Basilisk Collar, Gorgon's Head, Neko-Te, Lightning Greaves...

Also, these cards I don't think fit the deck very well.-Dark Depths.

-Riftwing Cloudskate

-Peregrine Drake and Cloud of Faeries

-Hunted Dragon and Hunted Phantasm

-Grafdigger's Cage!!! You should NOT play this card. It blocks out Melek and isn't of much use.

-Tormod's Crypt

-Staff of Domination

-Sun Droplet

-Claws of Gix

-Copy Enchantment

-Whelming Wave

-Acquire and Fabricate

-Hurkyl's Recall

The rest of the cutting you'll have to do in the burn package. Hope I helped, please check out my thopter deck:THOPTERS!!!!! .

I would take out all of the "copy target spell" in this deck, if you're trying to trim. Most of your instants/sorceries are things that don't really need to be copied (Temur Battle Rage, Reforge the Soul, etc). ALso, I'm not sure the utility of the Act of Treason effects, since you don't really have a way to capitalize on it (very few sacrifice outlets, etc). Some of your equipments may be redundant -- see which ones actually provide a win for you, and tailor the equipments to that.

Finally, I'd trim on your creatures -- if Voltron is your sole win condition, then you don't really need other creatures in the deck unless they provide extreme utility or protect you from opposing attacks. Purphorous, Rakka Mar, Akroma, Avatar of Fury...unless your meta demands it, I think you could find ways to trim these.

Good luck! Love the theme.

Ok so, apparently there's this combo... I heard it works, but I can't really wrap my head around it.

You use Act of Treason to take control of an enemy creature, he you give the creature back to your opponent with Bazaar Trader. At the end of the turn, Act of Treason resolves, but it comes back to you since technically, it was under your opponents control at the time...

It's really confusing, and I'm not %100 sure if it works or not. I've been looking around trying to fins out if it's actually a thing, but I can't find anything. I may end up taking it out all together, but if it does work, its super strong for this deck.
