Act of Treason Discussion

Sarkhan_Dragonclaw348 on Maelstrom Walker (needs help)

This commander looks like he's mostly there for the three-color synergy. There's also:

Mainly green: Surrak Dragonclaw (not great but works in creature-filled decks), Yasova Dragonclaw (niche-based and has built-inAct of Treason)

Mainly blue: Riku of Two Reflections (nice idea for supplementing the precon and likes spell-copying), Intet, the Dreamer (lets you play the top card of your library for mana symbol 2mana symbol u when it hits an opponent)

Balanced: Animar, Soul of Elements (already in your deck, better as a creature than a commander), and Maelstrom Wanderer himself. Although, he's a little green-oriented, I guess.

For the Wanderer, though, you're going to need two things: mana acceleration and flash enablers. If Prophet of Kruphix were legal, I'd suggest her, but as it is, Alchemist's Refuge works fine for that kind of thing. It would be pretty cool to scry a little, flash in a creature with cascade, and play a damage spell and copy it with, say, Riku, or counterspell their card. I think that scrying is definitely better than card draw in this deck, because you have those cards with cascade that get you what you want. I recommend Shardless Agent for that purpose. Nature's Will would keep your lands untapped for using Alchemist's Refuge on another player's turn.

It's a little tricky to recommend things, since I'm not entirely sure what your focus is, but I hope that I helped a little.

Hello again,

  1. I'm definitely not saying that your mana base is bad. I'm just noting what I saw, and even an extremely expensive base can end up flopping. I just looked at a deck with fetchlands but no basic lands, and even without seeing that kind of thing, I think it's better for the base to have at least a half-dozen of each basic land type, especially in bicolor decks, rather than hundreds of dollars in waste. The color pie on the right of the page here says things are just fine, so I'd go by that.

  2. I'm half-embarrassed that I overlooked two major rulings in that instance, but I do things like that too much, and I've learned to expect them. Oops.

  3. That makes sense, I guess. Myself not being a Magic connoisseur, there are plenty of cards--particularly the older ones--that I don't know about. In my experience, this seemed pretty powerful, but I'm not exactly surprised that there are plenty of cards that could shut down this strategy. There's one of those for each deck strategy ever conceived. I have a speficic red-black Act of Treason + Undercity Informer or Bone Splinters combo deck to shut down most mid-range or aggro creature decks.

Anyway, nice job on this, and I hope FtV: Lore gives us some sweet green-blue reprints for abusing counters like this!

Have a great day, or night, or something.

I personally am running a B/R aristocrats deck and one card I love in it is Insolent Neonate it has amazing synergy with Liliana, Heretical Healer  Flip and is a nice source of card advantage. I would suggest you add a couple madness cards to go with it however as that makes the neonate and Liliana's plus ability so much better. Cards like Fiery Temper or Malevolent Whispers (whispers could maybe replace Act of Treason) would be good on theme additions. You might want to look at other madness stuff as well.

Hello! Im seeing you are trying to do a budget deck, but you have some cards are not too good like Act of Treason. Try using sets of cards, 4 of the same Card. Judging for the deck you are new in the modern field look for a deck called stompy.

Hail Emrakul!

Gidgetimer like using Mob Rule, Act of Treason and then using Fling or other forms of removal?

is there a reason why you chose Act of Treason over Traitorous Blood?

13org on Need Help with some interesting ...

1 month ago

well i built some decks a while ago and needed a little help.

this one is almost finished. i dont see where i can improve it without sacrificing the the deck mechanics. sure, it is a little slow, but i have plenty of removals, and after some time, the victory is guaranteed.

Stolen Wealth
This one is still just an idea.Wanted to play with one of the most fun cards i have ever seen, Villainous Wealth specifically, targetting enemy players, using their spells and deck to kill themselves.

i tried to do a mix using this and cards like Traitorous Instinct and Act of Treason but it didnt work very well...
