Act of Treason Discussion

Calliber on Jund help

So, is your commander going to be a big mechanic in the way the deck plays out? Because right now, you could throw in most any other Jund commander without having much of an effect on the deck's mechanics. You already have a strong +1/+1 counter theme going, Kresh the Bloodbraided could work as the commander in that respect. But would could also work is Adun Oakenshield but may be a bit out of budget. This would not require your commander to even be on the field so you could put in someone else.

Going back to Sek'Kuar, Deathkeeper you'll want cards in the deck that are going to bring creatures back from the graveyard consistently. I'd recommend Persist/Undying cards for one: Puppeteer Clique, Furystoke Giant, Cauldron of Souls or Evernight Shade, Undying Evil, Pyreheart Wolf (possible win condition with enough creatures out) and such.

Another option with Sek'Kuar, Deathkeeper is to use Act of Treason spells combined with sacrifice options. You get a free attacker, if they don't kill it you can sacrifice it and get a 3/1. Removal, attack, and replacement all in one. Your current card options are not set up for this though and would require a big re-work.

Seeing as you focus on big creatures and pumping them up I'm going to say try working in evasion techniques to get those creatures through. Jund can easily give you a lot of Menace, Intimidate, and Fear options in that respect. But another that you did touch on a little in the cards was cards that make your creatures do direct damage to other creatures: Ulvenwald Tracker. Green has a lot of other cards that do this, and if you are pumping creature power then those cards will go a long way in enabling board control.

Overall, I love this deck. But why use Mark of Mutiny instead of Act of Treason? And I would add Thing in the Ice  Flip. How's Searing Spear working for you? I mean, it's clearly not as good as Lightning Bolt, but is Searing Spear a good replacement?

Hello I friend of mine played the deck against me today and it was great! I love this :D but i couldn't avoid feel like this can win more games with a bit more or reach, to close games before your oponent recovers or take the lead. Because of that i think that Rites of Initiation could be great here, as a 2x, to help you get that last, or lot bit of damage, cause if you time it right you can deal a lot of damage out of nowhere with that card. What do you think? I would maybe cut 2 Act of Treason cards

Well, it looks good for a 1st deck. You can thank your Uncle's friend ;). If you want to increase it's power, maybe you should look at other vampires like Bloodflow Connoisseur and Indulgent Aristocrat which work with Act of Treason (you can attack with an opponent's creature and sacrifice it), Olivia, Mobilized for War and Olivia's Dragoon to increase your discard mechanic, or Olivia's Bloodsworn to be more agressive, Olivia Voldaren to have more control. Anyway, this deck looks great.

Act of Treason, Act of Aggression, Mark of Mutiny, and Grave Betrayal are must haves in this deck. Because of the dethrone ability, the stolen creatures will stay yours. Thats is, if they die before EOT.

Hi SturWulf, thanks for your comment!

The reason I don't use any instance or sorcery spells to sacrifice creatures, is because they are less consistent. Say I have 2 steal abilities (Act of Treason) on my hand but only 1 Fling-like ability; This would make the second steal ability less useful.

Another good point is that comboing with Fling would require me to spend mana for a steal spell (3 or 4) in addition to Fling's 2 mana, which makes the combo slower. The one exception to this is of course Helm of Possession which also costs 2 mana to activate, but in that case the effect lets me handle two creatures at once.

Oh man, Ink-Treader is a beast...

I like Harnessed Lightning for massive damage, Otherworldly Outburst before a wipe, Spawning Breath and Make Mischief for small tokens, Rite of Replication or Spitting Image or Stolen Identity for good tokens, Saheeli's Artistry for good tokens and a ton of Sol Rings or other rocks, Act of Treason or Besmirch or Mark of Mutiny or Catch or Threaten to get control of everything for a turn, Press into Service to get control of everything for a turn and buff your guys in the process, Confiscation Coup and Dominate to get control of everything ever, Verdant Confluence to get every land from your deck or permanent from your graveyard, Supplant Form or AEther Mutation for the nastiest wipe ever, and Simic Charm for its amazing options.

On top of that, blue has nasty control and can create nearly infinite mana with cards like Dream's Grip and Ghostly Flicker. Not to mention you can draw your whole deck in all four colors with cantrips.

Here's to an errata'd legendary in the 4 color release, my friend.

Fear the Wojek Siren.

RazortoothMtg: I chose Hijack and Word of Seizing over Act of Treason and Threaten because of their versatility. You're right Besmirch is better and I didn't know about it. But I can just get more out of Hijack and Word of Seizing.

NoSoyYucateco: Weathered Wayfarer and Nykthos, Shrine to Nyx are a no go because of price. So unless the rest of the deck can get cheaper, then that's just out of range.
