Treasure Cruise and Monastery Swiftspear appear to be what a UR Legacy deck is looking for. Aggro and the ability to reload make an interesting combination.
To enable draw and discard, there appears to be several classifications of cards:
- Careful Study/Faithless Looting appears the best. It’s cheap and you get to chose what to discard. The downside is you net -1 card per time. This isn’t horrible if you get to cast a madness card off it. The other downside is they are sorceries 🙁
- Dangerous Wager is possibly ok. I’m unsure how often we’ll be able to live the dream with this but it will likely be card neutral and we may get value. I’ll also mention that it’s an instant so you can do it end of the opponents turn and leave countermagic up.
- Control of the Court/Goblin Lore/Desperate Ravings/Tibalt, the Fiend-Blooded all have random discard but are card neutral. The issue is that you can’t be 100% sure of getting your madness value out of it. I think that’s just too much of a downside.
- Wild Guess/Tormenting Voice are possible includes because you are card neutral. The downside to these is you may have it countered and just be down two cards.
- Compulsive Research/Thirst for Knowledge are possible includes. Complusive Research is the best option because we can throw away unneeded lands and/or madness cards (or madness+land).
- Catalog is like Wild Guess/Tormenting Voice only we don’t have to possibly go 2 for 1 if it gets countered and it’s an instant, but I’m willing to tap out on our turn to get a cheaper casting cost.
- Dack, Fayden is recurrable draw/discard, but I’m not sold. You can also steal Jitte/Swords/Batterskull if necessary (but you’ll have to re-equip except Jitte).

The one thing I dislike about the deck is it’s running blue, but there are no counterspells. I would happily jam a playset of FoW/Daze and call it a day.
I have found it consistently kills turn 4/5 goldfishing and turn 5 kills are when the opponent is at very low life turn 4 (under 3 usually). It’s also a blast to play and the card velocity is amazingly high so you see so much of the deck by the time you get to midgame.
