JXB on Tibor and Lumia take to the sky!!

Since Tibor and Lumia are very much centerpieces of your deck, you need to be able to do three things with them. - Get them out reliably - Protect them once they are out - Utilize their unique strengths. You did a good job on point three with providing a lot of ways to get value out of them, mainly by loading up on mass flyers. However, your deck seems to struggle with ramp and protection. As such, I would recommend Izzet Signet, Basalt Monolith, Fire Diamond, Sky Diamond, Talisman of Impulse, Mind Stone, Thought Vessel, Swiftfoot Boots, and Lightning Greaves. As for your spells, in my experience spellslinger decks need two things: Fuel and Hands. Fuel means they need a lot of mana while hands meaning the ability to draw cards effectively. Some good cantrips that could help you are Gitaxian Probe, Ponder, Preordain, Opt, Serum Visions, Cathartic Reunion,Tormenting Voice, Impulse, Mystical Tutor, Whir of Invention and Frantic Search. You also should have a backup plan. In spellslinger decks this means at least two ways to win out of nowhere. Enter the Infinite + Laboratory Maniac+ Omniscience, Dramatic Reversal + Isochron Scepter + Manarocks + Comet Storm Jace, Unraveler of Secrets's ultimate, and my favorite Dualcaster Mage +Fated Infatuation can do miracles. Also for fun, adding in Beacon of Immortality, Blue Sun's Zenith and a few mass draw spells can really kick things up a notch. As for removal Cyclonic Rift, Blasphemous Act, and Chain Reaction are the best ramp spells, while Mystic Confluence is one of the best modal spells ever printed. Tormod's Crypt can destroy decks with ease while Mizzix's Mastery makes life a lot more fun for you. I have never regretted running Sentinel Tower, Aetherflux Reservoir is a massive wincon, The Mirari Conjecture, Swarm Intelligence, and Metallurgic Summonings can win games by themselves. Also look at Jace's Sanctum for more fun and games.

I would generally argue for Goblin Electromancer and a few mountains over Jace's Sanctum for budget players.

The term for this deck is High-Tide Mill.

RazortoothMtg on Pattern Recognition #79 - Ravnica's ...

I think it's important to note that Test of Metal is mostly regarded as non-canon at this point for various reasons.

Also, as for extra ravnica-based stories after RTR, other than the one where the gatewatch sits around Jace's Sanctum and Dovin Baan shows up, the one with Mazirek, Kraul Death Priest was pretty important. I've forgotten enough details that I probably can't summarize it well, but Jarad, Golgari Lich Lord's second in command guy gets a note from the Kraul, who are pretty downtrodden when it comes to politics within the guild, and the Kraul kill him or something. Also Vraska the Unseen and Mazirek are apparently best friends and she's gonna make them the top of the guild when she gains control of it. Wasn't there a bit at the end of Ixalan block where Bolas had kidnapped Jarad to fulfill his promise to make Vraska the Golgari Guildmaster?

Here's the link to the Mazirek article if anyone's interested, since I probably got it very wrong. https://magic.wizards.com/en/articles/archive/magic-story/pride-kraul-2017-05-31

I suggest Jace's Sanctum, Curious Homunculus  Flip, Goblin Electromancer, and Baral, Chief of Compliance to make the casting cheaper, and homunculus can work as a heavy hitter because of prowess

@hardhitta71194 I get ya man, apologies for if I was coming off as an ass anywhere also.

My playgroup is a group of 5 all of which are friends I grew up playing magic with, plus my wife, and we are all VERY competitive. It's hard playing control in a pod that's 5-6 players I get it, but... You learn which cards absolutely CANNOT stay on the table or even hit the table and burn/counter those into oblivion lol.

Honestly I think locust god would be really good for you, and then just run a lot of spell reduction in place of Mizzix like Jace's Sanctum and stuff.

Also since I know you love tokens, you should 100% play Metallurgic Summonings. I don't play tokens but I run it because it produces great blockers, offers an alternate win con, and that second ability is SO strong.

Sensei's Divining Top will do nicely with Galvanoth and Melek, Izzet Paragon; or maybe Crystal Ball, Eyes of the Watcher and/or Jace's Sanctum as low cost alternatives.

Neotrup on Can Elite Arcanist cast copy ...

4 months ago

No. Jace's Sanctum has no effect on anythings converted mana cost. Elite Arcanist chooses the value of X based solely on the exiled cards converted mana cost, not on how much you'd actually have to pay to cast the spell. If Elite Arcanist has exiled Wizard's Lightning it will cost to activate it's ability and cast the copy, even though it is a wizard itself. Anything that alters the cost to activate abilities, such as Heartstone will apply to the activation cost however.
