SacredAtsira I encourage you to try it out. This deck is an absolute blast to pilot. Considering the difficult time I had making cuts means there are options to make it your own. My first draft of the deck combined the Party mechanic, so maybe that’s a road to explore. I appreciate your message and wish you luck in whatever decks you build in the future.

Tortured Existence is a card that was pretty much made for a Sefris deck. Radiant Solar is a great way to race through dungeons. And Tomb of Horrors Adventurer is a spectacular pay off for finishing dungeons. Coveted Prize could be a great pay off for your Party co-theme, and speaking of your party, might I recommend an honorable warrior, Tenacious Underdog.

Comet Storm could be a great way to spend all that mana you’re gonna have. Tyrant's Familiar is a nice pay off, especially if you only have your background out. Budget didn’t seem too much a barrier for most of your other choices so I’m surprised not to see Ancient Copper Dragon as it fits Dragons, treasures, and Bauldur’s Gate all wrapped up into one card. Frontier Siege is another one to look into. Lathliss, Dragon Queen and Dragon Broodmother will help you pop out more dragons to get more treasures.

Also Seedborn Muse can make it so you can cast all the instant adventures and Alora, Merry Thief can not only get your creatures through, but then return them to had to recast the adventure spell side all over again.

I’m surprised to see all the swords, but not the equipment that actually has an advent On it, Horn of Valhalla. Sailors' Bane is a wonderful payoff for casting as many adventures as possible. I’d also be concerned about how little ramp you have in the deck. Since the permanent side of an adventure is usually overcosted, and you’re going to be wanting to cast as many adventures as possible, so ramp is going to be extremely important to making the deck work. You may also want to add in a tad more removal, especially a board wipe or two. Tragic Arrogance would serve you here. And just a bit curious why you added Ellywick Tumblestrum as it doesn’t seem to fit with anything else you’re doing in the deck.

I know you’ve been trying to use cards you already have on hand, but there are a few cards you may wanna consider picking up: Coveted Prize can be an all star here. Tribal spells work fantastically in a party deck. Two of my favorites that have served me well in my own Party Time upgrade are Cloak and Dagger and Obsidian Battle-Axe. Irregular Cohort and Mage's Attendant can really help fill your party, and Shields of Velis Vel can turn on not only a full party but any tribal synergies you’ve got going on. Hope at least some of that helps. Party on!
