Act of Treason Discussion

GoldenDiggle on Thank God This Isn't Legal

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.

No prob brotha, have a few more suggestions too.

Should up your land count to 25 to ensure you can get your 5 drop out on turn 5. Haven of the Spirit Dragon would be great here. Flooded Strand would be much better here than Heath. Not exactly budget but perfect for your colors. Also, Act of Treason probably isn't necessary. With your big creatures outclassing your opponents' or just flying over them, you would be better served having more removal spells and burn spells to hit them in the face, like Wild Slash. Stubborn Denial is a seriously underrated counterspell. All you need is a single dragon out and its a unconditional counter to all non creature spells, great at keeping your dragons alive.

That's all I have for now, but I love playing dragons and will probably drop in with more suggestions from time to time :p

Someone might have pointed this out already, but Besmirch is strictly better than Act of Treason and Threaten if the double red isn't a problem.

I am in the process of doing the same thing.. well testing phase and I have a these in min.

Act of Aggression, Act of Treason, Besmirch there are a few more but those are the only ones I can think of.

you need to protect yourself from decks that plan to use Act of Treason and other betrayal cards. I suggest using Melira, Sylvok Outcast

I agree with Sergal here. You have way to many Act of Treason cards here. While annoying for some decks that rely on creatures you may be completely dead to decks that don't play creatures. Im down for this plan but only if you have a really strong plan B that you can pivot towards if the matchup is not good. Not sure what that is since Mardu isn't a terribly popular color combination in Modern but I think you could do some kind of sideboard transformation into tokens or burn. Tokens with Young Pyromancers and Lingering Souls or burn with cards like Lightning Helix and Boros Charm. Replace all the Act of Treason cards for these after sideboard for matchups that are not good for Act of Treason.
