You can use double square brackets around a card's name to create a reference link: Scion of the Ur-Dragon, Savage Ventmaw, Old Gnawbone. It's the best way to make sure everyone understands what's going on in the question.

No, it won't work that way. Scion of the Ur-Dragon's ability doesn't create an extra copy of the dragon you choose, rather it makes Scion become a copy of that dragon until end of turn. When Scion becomes a copy, it will just be that dragon and won't have its normal printed abilities or the printed abilities from something else it may have been a copy of earlier in the turn.

You can use Scion's ability in a way that makes it become multiple other dragons in sequence, but in the end it will just be one of them, not all of them. Sometimes this can be useful, like in a combo where you activate Scion, immediately respond by activating it again, get Moltensteel Dragon with the first activation that resolves, respond by pumping up its power before the other Scion activation resolves, and then for the other Scion activation get Dragon Tyrant/Skithiryx, the Blight Dragon and the +X/+0 effect you created will carry over. In your example, there's nothing that will carry over between Savage Ventmaw and Old Gnawbone.

Some synergies to consider: Cryptic Gateway, Ruby Medallion, Emerald Medallion, Nogi, Draco-Zealot, Sarkhan, Soul Aflame, Taigam, Ojutai Master, Guardian Project, Toski, Bearer of Secrets, Steely Resolve, Thornscape Familiar, Ancient Copper Dragon, Goldspan Dragon, Cavern-Hoard Dragon, Terror of the Peaks, Scion of the Ur-Dragon

I know most of these aren't Dragon's but when you're trying to quickly fill the field with a bunch of big ole chonkers, you need cost reduction and Ramp! I'd also recommend more Rocks and Dorks to that end, as well as a few and/or rituals. I could easily see this build being overwhelmingly threatening within the first 5 turns of the game if tweaked a bit.

May I suggest running Scourge of Valkas as a target for Scion of the Ur-Dragon, or Zirilan of the Claw?

You will have a near 50% chance to kill the entire table with Scourge of Valkas + Ancient Gold Dragon

Hello! Thank you for the comment. There was a time, early in this deck's inception, where Teneb, the Harvester and a couple of Dragons with similarly-costed activated abilities were in the build. Over time, it became apparent that Teneb was never a target for Scion of the Ur-Dragon's activated ability. The deck continues to evolve, as more and more powerful Dragons are created constantly. The Dragon-pecking order is reassessed after each new set that releases, and it has become more strict and more difficult to earn a spot. We want Dragons that can deliver hay-makers to our opponents. Unfortunately, Teneb does not do this. Swinging for six points of damage and recurring a Dragon for a total of five mana (two for activating Scion and three for activating Teneb) is just not enough these days (frown).

Unfortunately, no. Scion of the Ur-Dragon's ability has an "until end of turn" duration. Scion's effect ends when the duration of the ability ends, which is at the end of the turn during which Scion's ability was activated. Even if the card is phased-out afterwards, it phases-in as Scion.

Unfortunately, no, but I wish it would! Once Scion of the Ur-Dragon becomes a copy of Ancient Gold Dragon, it loses its original activated ability, becoming an exact copy of AGD. Although Scion's ability can be activated in response to an activation (i.e. the Moltensteel Dragon + Skithiryx, the Blight Dragon combo), once Scion becomes a copy of a Dragon, that ability is lost until the next turn. That would be a sweet combo though!

Thanks so much for this! It is incredibly helpful. I am glad to hear the deck is performing better, and seven out of ten is a good rate and consistent with what I've seen. It's also super cool that you got off the combo with The Book of Exalted Deeds and Mutavault. While not the sort of thing that likely happens often it is super powerful when it does! I especially appreciate the insight on Emeria Shepherd since I have it and have pondered putting it in, and it certainly is better than Karmic Guide for only two more. My recent update (which I need to post) cut two five drops for a three and a four drop, so raising it 2 on one card definitely seems worth it. Nykthos, Shrine to Nyx is also one that belongs in the deck- my only copy is in my elf deck and I don't like proxying, but there is no reason not to put that in. Crucible of Worlds with fetches is also a solid choice in any non-green deck. Teferi's Protection is also great and I only don't have it because as with Nykthos, my copy is in a different deck, but that can easily replace Guardian of Faith or Cosmic Intervention.

I do like that this deck plays pretty differently than my other decks and is a true, "fair" aggro deck. Among my other decks three of the more aggressive decks, Scion of the Ur-Dragon, Yuriko, the Tiger's Shadow, and Ezuri, Renegade Leader are much more tool-boxy and tutors are huge. Really only this deck and my Trynn, Champion of Freedom/Silvar, Devourer of the Free deck play a classic aggro game. It's fun to play aggro, be powerful, and be resilient.

Thanks again for all of your playtesting and feedback, it is super appreciated!
