Roon of the Hidden Realm Discussion

Feyamius on Welcome, to Jurassic Park

Yep, Signets are generally considered better in EDH than Cluestones. They only cost two instead of three and you almost never sac them for carddraw, bc it's just one card, it costs two mana to activate and you lose your ramp. It's good only in a situation where artifacts get boardwiped and your cluestone is untapped and you've got the mana open to activate the sac. That's why Commander's Sphere is a much better three drop ramp. In case of emergency, you can sac it no matter what.

I'm only considering cluestones in my mega-budget build with Roon of the Hidden Realm, so that a blinking Trophy Mage can find them all.

First off, I love this. Lore is so deep in magic and its always a joy to see someone else making it part of their game.

Secondly, I'm almost sure that Roon of the Hidden Realm is from Bant, given that he's a rhox soldier with what appear to be sigils.

Great list!

@Barsan Thanks for clearing that up, the rules on morph are a bit strange so I wasn't sure.

Wow, never even heard of Fractured Identity, Ill definitely try and find a spot for this. (It's so mean with Phage the Untouchable, I love it XD).
Roon of the Hidden Realm is a interesting one. He does provide a lot of useful utility, but I'm not sure if I have enough cards that work well with him to make him worth it. I'll definitely give him a try though.
Sundial of the Infinite is kinda in the same boat as Roon of the Hidden Realm (obviously it would work better if I included both of them). I do like how easily accessible it is, I think almost all my tutors can hit a two mana artifact.
I think I'll end up just cutting Voidslime. Thanks for the note on Disallow though.
I know Felidar Sovereign is cheesy in EDH, but the fact that my opponents always have to look out for it s partly why I use it.

Thanks again for all the great suggestions.

@Exxie97 He is confusing flipping and flickering. Flickered Creatures leave combat and have summoning sickness, Flipped creatures do not.

Roon of the Hidden Realm exists in your colors and can be used to unflip specific creatures after your opponents swing out, as a means of defense, or to repeat powerful ETB Triggers such as Ixidron and with Voidslime's stifle effect, or Sundial of the Infinite (Which can also prevent detrimental ETB effects) you can permanently exile creatures... even Commanders.

Phage the Untouchable in an Esper capable deck kind of begs for a Fractured Identity doesn't it? Especially considering you run Eater of Days.

Disallow is a strict mana cost improvement on Voidslime

I absolutely hate that Felidar Sovereign is allowed in EDH. At least a Phage Textwin is risky.

colton815 on Stack interractions + Layer interractions

as for your Roon of the Hidden Realm, yes its ability resolves. i'm not sure why you would question that.

as for your second scenario, that is also mostly correct. the base p/t would be 1/1, but it'd still get the bonuses and be a 9/9, and the ability to destroy a permanent is an ability of the equipment, not the creature its equipping. otherwise it'd say "equipped creature gets "..." "

Shape_Shifter on Stack interractions + Layer interractions

So recently me and my playgroup have been getting deeper into magic rulings (Priority and creature layers and what not).

During this we found that we may have been doing several things wrong before and i'm just trying to confirm wether we now have the right idea about it all.

Stack interractions: Before learning more about this we often had a situation where I had for example Roon of the Hidden Realm out on the battlefield and was going to attempt to use his ability to flicker one of my other creatures. My opponent at that time would react with Sleep for example, tapping roon and saying 'now you can't tap it for its ability'. Untill learning about Priority we always thought this was an OK interraction.

However the new view would be: I have priority, I throw my ability on the stack (tapping beeing a cost for it as well, so it can't be interrupted). I then pass on priority to my opponent who casts Sleep.His sleep will resolve first, but my creature was allready tapped as part of the cost, and my ability still resolves as well. Is this correct?

Layer interractions: Before learning about layers this situation would happen:I have a 2/2 creature equiped with Argentum Armor and lets say it also had 3 +1/+1 counters on it. I move to combat, declare attack with 9/9 creature.At this time my opponent casts Turn to Frog, declaring that my creature is now just a 1/1 and the argentum armor trigger doesn't activate since 'it loses all abilities'.

After looking into layers, we now think that this interraction would do close to nothing for the opponent as base power adjustments happen first, then the boosts happen (counters, equipment boost) and on top of that is the trigger from Argentum Armor still valid as well.Leaving me with a 8/8 creature. Is this correct?

Thanks in advance :)

DemonDragonJ no problem for my name. By the way, I've seen you listed Roon of the Hidden Realm from Bant. Even if visually he seems a Bant rhox, I don't think it has been evere confirmed.

Eldrazi Displacer, Roon of the Hidden Realm, Mistmeadow Witch, Crystal Shard, Dissipation Field, AEther Adept, Reflector Mage, Man-o'-War, Tradewind Rider, Vedalken Mastermind, AEtherize, AEtherspouts, Evacuation, Cyclonic Rift, Devastation Tide, Deputy of Acquittals, and Brago, King Eternal are just a few suggestions.

Be wary of Eldrazi Displacer because he requires colorless mana to activate. Sounds like a cool idea with a bunch of ETB effects on your creatures so if your opponent is creature lite you will still be effective. Lavinia of the Tenth would be a cool general that would be obnoxious to go against. Especially against a deck that utilizes a bunch of mana dorks. Also good for the mirror match. Deadeye Navigator is a total must. I know someone else mentioned him, but if you do get him on the board he's so broken. Another idea would be to play Mimic Vat having recurring creatures of you or your opponents sounds legit.
