Scion of the Ur-Dragon Discussion

TaegukTheWise on Roon Blink

Utility lands are a great substitute like Reliquary Tower or a pain lands like Yavimaya Coast, however they aren't basics which is the important part and the only reason I recommend them. Unless you had a creature like Ulvenwald Hydra (even though he is a good finisher I would recommend) that you can get out early and often to get any land, it would be hard to tutor for them otherwise (aka get them often enough), that and Blood Moon/Magus of the Moon turn them into mountains, rendering them useless. If you also had enough card draw it would get some of those cards, but its not as reliable as having a bunch of ramp spells like Rampant Growth, Kodama's Reach, Explosive Vegetation, and even a land that can even sit there and produce colorless; Blighted Woodland that for very cheap, can get the basic lands that you need and put them directly into play. However in one very specific case (albeit a more rare case than blood moon by a HUGE margin) Sundering Titan, the controller has to name every basic on the board and they are gone, which is another reason why I run fetches and dual lands that can be fetched, other than their enormous help with fixing when I need them. The only decks that will ever feasibly play this is either a Daretti, Scrap Savant deck or a prison style deck, which you should be trying to kill first anyway. I recommend more basics because they are easier to get out of your deck, nothing feels worse than to top deck a land when you really needed a removal spell, or to have a counterspell up for defense, but that's my take anyway, and it works out great for me since I happen to thin out my deck each time I play my Roon deck.

KEEP IN MIND Adding those wastes will basically turn your 3 color Roon deck into a 4 color deck. You will need to get at least one waste per game in order for you to get some form of value when you do play your displacer. The other upside to adding Wastes include: not being a good target for land destruction like Strip Mine, they are basics, and are under a dollar on sites like amazon. Downsides include: Adding another color to your deck, and lowering the amount of actual fixing for fetching a wastes. I feel the downsides are rather negligible since they should be the last land type you should fetch for after getting your colors. Except when it comes to opening hands, but that's highly dependent on other factors as well since they are still lands that actually do something when they come into play. If you aren't running Thought-Knot Seer then I would recommend 3-4 wastes if you do consider getting them (and 4-6 if you do get the seer). I would trade them with the ravnica bounce lands: Azorius Chancery and Selesnya Sanctuary along with Temple of the False God (since its never good in your opening hand nor when you can actually use it) and Secluded Steppe because its bad, especially for a 3 color deck.

Also, Opal Palace isn't that good here. Its more for voltron style decks, or decks that have a commander that gets removed a lot like Scion of the Ur-Dragon, Mana is pretty precious. Washing some colors can be cool, but that's like adding an extra (1) to every spell you play because you need to tap an extra land. I have also gotten the prebuilt Derevi commander deck, its what I used to build my Roon deck. I used to run Rupture Spire and Transguild Promenade as well, but I find that they slow me down WAY to much for what they offer in return, they are even worse when I have both of them in my opening hand. For all 3 of these I would just put in a regular forest, plains, and an island in their place. That's how bad I believe they are, if you want to add other utility lands in there or more wastes, be my guest, but I would strongly urge against these 3 unless you absolutely NEED that kind of fixing.

Also, no problem! I love deck doctoring, especially when it helps another Roon player :D

Just ask and I can answer other questions or provide more advice. I have this very terrible habit to mid-max my decks...

Another Mirror question: Can you target Scion with Mirror of the Forebears when it's between 2 stacks of its' ability?

For example: I have 2 copies of the mirror, and I turn Scion of the Ur-Dragon into a Hellkite Charger, then respond so that it turns into Savage Ventmaw first. Can I respond to it becoming Savage Ventmaw by turning the 2 Mirror of the Forebears into copies of Savage Ventmaw and still have Scion turn into the Hellkite Charger?

WanderingSpirit on Scion of the Voltron? [Brewing]

2 weeks ago

I'm working on an enchantment Voltron deck helmed by Scion of the Ur-Dragon. It features all of the cheap 'this god lokes you' enchantments like Steel of the Godhead. If you could get all of these on Scion, he would be ridiculous. I have never played enchantment heavy commander decks, but this is what I have so far: The Gods Love This Dragon!

Right now, the idea is to self-mill into something like an Open the Vaults while keeping Scion up with pillow fort play and dragons that are evasive to removal. What do you all think? Got any ideas?

wipperwhill123 on Scion Druid Win

2 weeks ago

As a Druid player, Skithiryx, the Blight Dragon is a late-game finisher. You cast Scion of the Ur-Dragon, use his ability twice to get Moltensteel Dragon (pump +6/+0 with 12 life), then get Skittles. This makes Scion a 10/4 flying infect. Protean Hulk requires too many cards that don't do anything without the hulk himself, and you'd rather just tutor for Hermit Druid. I took Cephalid Illusionist out because my version doesn't play enough creatures to support the combo, and rather just play more ways to get hermy back if it dies (would highly recommend Claim / Fame). Necrotic Ooze doesn't need haste because Devoted Druid, Morselhoarder, and Niv-Mizzet, the Firemind don't need to tap to make infinite mana. To answer my own question from a lot earlier, Caustic Caterpillar is good if you topdeck a creature tutor and have to kill a Leyline of the Void or something.

DRACULA150704 on Scion + Master of Cruelties

Ok thanks- so I should transform Scion of the Ur-Dragon after attacks but before blocks?

Neotrup on Scion + Master of Cruelties

4 weeks ago

They will take 2 damage. If you instead declared the attack and turned Scion of the Ur-Dragon into Master of Cruelties, then they didn't block, that would kill them. Master of Cruelties ability triggers during the declare blockers step after blockers are declared just before any player receives priority, so in order for it to trigger it must already be on the battlefield in that form when blockers are declared.
