BMHKain on Help Needed for Pramikon, Sky ...

What does The Wall need for more Malice? MURDER.

Commander / EDH* BMHKain


(Disclaimer: There is a Sound Reason I didn't choose Arcades, the Strategist; it would make Deckmaking of this direction FAR easier. I will also NOT make a Nicol Bolas, the Ravager  Flip or Chromium, the Mutable deck as both are also very viable in their own ways. Leaving only Palladia-Mors, the Ruiner, & Vaevictis Asmadi, the Dire to choose for my resident M19 Elder Dragon. Oh, & I won't take Dragon Tribal as an Option; that's The Ur-Dragon/Sarkhan Unbroken level OP; & I thought the Former was supposed to be stronger than all 5 remaining Elder Dragons; reduced to one being trapped in his own Meditation realm w/ Ugin no way in, and/or out. I'd love some suggestions for either of the worst 2 Elder Dragons as CMDR if anyone is interested. :) Just make sure the ideas a Viable enough, & post how you'd make your C19 Version "Non-Dragon Tribal/Non-Nicol Bolas/Arcades/Chromium" Palladia-Mors or Vaevictis Asmadi CMDR, just suggest some ideas on my Wall, & we'll talk.

Also, If isn't my Tertiary Color, maybe is? I still wanted to finish my Color Identity Roadmap after over a year since staring. That, & I wonder If I'm a Denizen of Raugrin/The Jeskai Way if so?

(No really, though. On to the Real Topic; & I haven't made one in So Long, I just wanted a decent reminder on rulings. Thanks.)

Arcades, the Strategist? NOPE.

Doran, the Siege Tower? WRONG.

When it comes to Toughness Matters CMDRs, Pramikon, Sky Rampart would be literal Wall Tribe Lord incarnate that's the closest to Tribal Commanders on a Niche status (We got Hydra Lord now, & It creates so many on the fly.), but I'm not here for yet another Tribal Commander, I just wanted help for one thing right now:

(How do I make a Toughness Matters) deck in //? Commander: Pramikon, Sky Rampart. In spite of my Efforts, the First thing I need help w/ is:

1: Is there anything in MTG's entire Glossary of stuff that's good for Toughness Matters in ?

2: Notice most of my High Toughness Creatures aren't simply there as Defenders. Most actually have great abilities; & even don't have to be Wall Card Type to be so. Do you see this as a good idea, or not? This is very important if you're viewing my deck at incomplete status.

3: This is planned as a Toughness Matters deck, but some of the cards seem to show a Sub-Theme (Drannith Magistrate (HE'S NOT THE UNLUCKIEST. CEASE DEBATE. XP), & even Peregrine Drake.). Since this isn't the conventional Toughness Matters Deck using Defender more than I should, what do you think might be good here?

Honestly, I dunno what else to ask; maybe I'll add more questions overtime. Thanks for the help if you can; Obviously, this is a Pramikon, Sky Rampart "Toughness Matters" deck, but I'd rather Talk less of / (Golgari Swarm), & talk nothing at all about Doran, the Siege Tower as well as Arcades, the Strategist; I just want to experiment on a good Brew. Any ideas that can help? Thanks again. :)

(& sorry for the Huge Wall back there; I didn't think I wanted help again. X/)

NeonEndymion Just getting around to look at your comments in more details now.. I remember looking at Magmaquake earlier and it would be great if it wasn't for that double red mana and Jegantha... lol

Considered your advice and made the following changes: Feels like it made an overall improvement to the deck, I will add Dragonlord Silumgar and Fire Covenant when/if I manage to get my hands on them. Thanks again for the help.

In: Heroic Intervention - Out: Arcane Denial

In: Steely Resolve - Out: Path to Exile

In: Morophon, the Boundless - Out: Chromium, the Mutable

In: Ramos, Dragon Engine - Out: Hypersonic Dragon

In: Steel Hellkite - Out: Spellbound Dragon

In: Rhythm of the Wild - Out: Negate

There's enough decent non-red dragons at this point that I don't see the need to run a 4th color.

In Esper, Alela, Artful Provocateur is a weird kind of lord for all fliers, not just fae. Chromium, the Mutable is probably the best of the Esper dragon commanders, since his power aligns well with commander damage.

In Bant, Chulane, Teller of Tales is a pretty powerful ramp and draw engine for a creature-based strategy. The dragon options are... not great.

Teneb, the Harvester is the obvious choice for Abzan. Reanimator and graveyard strategies have good overlap with cards like Boneyard Scourge and Fearsome Awakening, so it's not a bad accompanying strategy.

Sultai doesn't really have great fits, as far as I can tell, but it's just overpowered in commander to the point of being a problem, so I'd say don't be part of the problem.

Would Chromium, the Mutable be a good fit for the deck?

Okay, This is how equipment behave.

The equipment will stay on the creature for as long as it lives. When Chromium, the Mutable changes, the equipment will still remain attached until you decide to attach it to another creature.

In short, the equipment that is attached would remain onto Chromium, the Mutable for as long as he/she doesn't get killed.

Hi multimedia,

Thank you for all of your suggestions.

Let me explain why I run some of the cards you consider cutting (Even though you're probably right and I will probably try it like you made it) The main reason why I am playing so many tapped fetches and tapped lands is to make the deck slower intentionally. It makes my opponents in my play group see me as "less of a threat". I don't mind playing slower so my end game can be more explosive. I was also playing these slow fetches and dual lands to have more mana with Prismatic Geoscope though I believe that you already saw irdue to the fact that you would consider cutting it. I usually fetch two basics when I know I don't need the duals for now making me able to fetch check duals and have them enter untapped.

I play Chromium, the Mutable because my meta has some heavy counter/control decks out there, so it helps to have him sometimes.

Regarding tutors like Eladamri's Call I tend to not run many, if not any tutor, in my decks. Maybe I'm not smart, but I like to play the top for my deck. Luck of the draw I guess. I do understand why you would want to tutor some of those dragons though.

I do need to ask why you would cut Zendikar Resurgent though. It seems great in my opinion, more mana to cast my big creatures and card draw on the top of that sounds great. I might be wrong thought.

All of your other suggestion are fair and I see why you would make the changes. I will try the deck with your changes on some nondescript application. If you have anything else for the deck, I would love to hear it!

Rhadamanthus on Chromium the Mutable--is discard necessary?

Use double square brackets around a card's name to create a pop-up: Chromium, the Mutable

You're not required to use the ability if you don't want to. An ability that's written like "[cost] : [effect]" is called an "activated ability". You activate it by paying the cost, and then you get the effect. In most cases you can activate an ability like this any time you'd normally be able to play an Instant spell.

The value of Chromium the Mutable's ability is that you can use it to protect Chromium from certain kinds of spells and abilities. The "hexproof" ability given by the effect means Chromium can't be the target of spells or abilities your opponents control. You can activate Chromium's ability in response to an opponent's spell or ability that targets it, and Chromium will be safe.

Please link cards with double square brackets to make it easier to understand the question.

[[Chromium, the Mutable]]

Chromium, the Mutable

Chromium's last ability is an activated ability. If you want the effect (the part after the colon), you activate it by paying the cost (the part before the colon, which in this case is discarding a card). If you don't want the effect, don't activate it. You don't have to activate the ability to use Chromium.

This means you either have a Flying 7/7 dragon (chose not to activate the ability), or a Hexproof 1/1 human (chose to activate the ability).

It's important to note that if you have no cards in hand, or something else preventing you from discarding cards somehow, you can't pay the cost for Chromium's ability and thus can't activate it.
