Act of Treason Discussion

Tyrant-Thanatos on Mind Control on my regenerable ...

This has pretty much been covered but to reiterate: Regeneration does not tap the creature until it actually replaces the event of death. Control changing invokes Summoning Sickness. This is why cards like Act of Treason specifically give the creature haste, because otherwise the creature would never be able to attack or use tap abilities since they are only taken for the turn.

Argy on First deck you Built

2 weeks ago

Mine was Mono and scrounged together from cards I had cracked from packs, and picked out of the singles pile at my local shop.

24 Lands (all Mountains), 24 Creatures, and 12 Non-Creature spells, as per online instructions.

The centrepiece was the first card I ever bought, Stormbreath Dragon. It cost me a grand total of AU$15. About US$20.

It had a good curve, starting with Akroan Crusader, moving into Dragon Hatchling, Young Pyromancer, and Guttersnipe, then finally Chandra, Pyromaster, and a dose of Lava Axe to finish the party.

It also had some copies of Act of Treason, which my friend used to HATE.

It won a few games, despite me missing almost every single trigger!

so looking at some of the Black Friday deals i decided it would be great time to build a strange deck.

Sundial of the Infinite

i liked the idea of flickering and cheating creatures(common of the blue white) and make copies that don't leave (were talking about you Kiki-Jiki, Mirror Breaker and Act of Treason)any and all assistance would be great.

Have you thought about running Act of Treason effects? That way you can steal people's creatures and then throw them with Brion. Zealous Conscripts and Mark of Mutiny are some good ones that come to my mind

I think that a lot of Commander players have a bias in that they perceive what they are doing as fine and what their opponents do as problematic.

For example, I have no problems with playing an Ink-Treader Nephilim deck and ending every game by casting Act of Treason on my Commander. (Also, make sure your group is okay with using Nephilim as Commanders). Other players may disagree. I've also run a Heartless Hidetsugu deck where I played quiet until I judged the time was right and then killed everyone in a turn. From my end it was about playing crafty and carefully manipulating life totals, watching untapped land and waiting to spring the combo on people.

I have a friend who's made Kambal and Nekusar decks. After a few games I hit on the strategy to deal with him: Kill his Commander every time it was played and/or kill him first. We had a good discussion about it though, where I laid out that the optimal thing for me to be doing in this games was eliminating his Commander or eliminating him. In the end I would like to think we've somewhat compromised. He has other decks and I've developed some counters to his decks. He doesn't play the decks I hate as much and when he does I don't focus him unless he "deserves" it. That was really the thing that prompted the discussion: I tried to keep him down and he kept saying, "Why me? I haven't done anything!"

So my advice would be that if you have someone in your group that you're on good friendly terms with you should have a discussion about what you feel like might be an unfair thing to do, but seems like the most reasonable counter to their decks. It worked for me.

"This will be done by amassing a steady stream of creatures, stealing my opponents creatures" Forgot this part. Here are some spells that can help with that:

Act of Treason, Slave of Bolas, and Grab the Reins just to name a few.

Nice try here, a word of advise,try and find what your deck is going to do,it seems like you want to do a little too many things at the same time,like steal your opponents creatures and playing your own,and destroy lands!

I suggest cutting on the Act of Treason effects all togetherInstead of destroying your opponents lands ,why not use ramp like Harrow or Rampant Growth and playsets (or 3 ofs) of Kinjalli's Caller , Drover of the Mighty ,Otepec Huntmastersome nice cheap dinos to consider :Ranging Raptors,Charging Monstrosaur, Kinjalli's Sunwing ,Goring Ceratops,Verdant Sun's Avatar,Wakening Sun's Avatar,Thundering Spineback

some other spells that go with the theme :Dinosaur Stampede,Commune with Dinosaurs,Savage Stomp

about the lands,the desserts don't contribute to your plan,try some cheap tap lands like Jungle Shrine,Rugged Highlands,Blossoming Sands,Wind-Scarred Crag or go the extra mile and hit some check lands like Rootbound Crag,Sunpetal Grove,Clifftop Retreat

Hydronvanquisher on How does Sudden Spoiling affect ...

2 months ago

Hi all, I've been reading up on Sudden Spoiling for a little while now and believe I have a basic understanding of it. However, I am still a little confused on how it would play out in the following scenario:

My opponent is the active player. Let's say I have a Zulaport Cutthroat and a Butcher of Malakir already out on the battlefield and my opponent has Void Winnower, Prized Unicorn and a Skyrider Elf on the battlefield.

My opponent decides to attack me with everything. After he declares attackers, and finishes casting any spells, he passes priority. I presume this is where I would either declare blockers or cast an instant and then declare blockers.

Could I cast Sudden Spoiling and then since the spell temporarily negates the static ability of Void Winnower (meaning I can block with an even CMC creature), declare my two creatures as blockers and then proceed?

I'm assuming I can but wanted to confirm I wasn't overlooking anything.

As a new wrinkle, what if during my casting step (prior to declaring blockers and prior to casting Sudden Spoiling) I decide to cast Quicken and then Act of Treason on his Void Winnower? I then decide to cast Sudden Spoiling and let combat proceed. What happens to his already declared Skyrider Elf if the CMC is even? He's declared it as an attacker but now that I have a Void Winnower on the battlefield (albeit temporarily) under my control, is it still an attacker or does it remain tapped but no longer have the ability to proceed to combat damage?

Sorry if this is a bit convoluted but I wanted to make sure I have an understanding. Thanks for any advice/info you can all offer.
