I am not really sure of myself, but it seems like you are trying many different things with this one. It seems so fun to play though ! Really ambitious, I like it.
Okay so maybe, for the spellslinger side of things, I think you might want to consider putting a Ruby or
Sapphire Medallion instead of another ramp card (Maybe the
Fellwar Stone ? I am not sure.). It might help you a lot when casting all those spells in one turn and might even be of a greater help than the Talismans. Also, Jori En is a wonderful card engine. (Let's you draw cards during your opponents turn if it's your second spell
)
Then, I a am not really sure about the Zada effects. Sure, it's really great when it works and it combines well with your cantrips, but they have to be played and stick for an entire turn to be really helpful, and because your deck won't have much creature, the opponents might save their removal just for them so ... I don't think they are that much of an help, but it really depends on your meta. If it brings you fun (and I am sure Zada and
Mirrorwing Dragon delivers in that category), let them in ! Same goes for
Thousand-Year Storm. It's an enchantement that costs 6 and does nothing the turn you play it, most of the time, so it's hard to get value from it (and that's sad because I want that card to stick a turn so baaaad !!).
It's just my opinion, but I feel like cards like Subterrean Tremors (love the art, but RIP your tokens) and
Soulblade Djinn are not that good in that deck. The first one seems like a nonbo, and the second looks a bit too much win more.
So, if I were you, I would take away :
-
Zada, Hedron Grinder -
Thousand-Year Storm -
Mirrorwing Dragon -
Crimson Wisps -
Expedite-
Fellwar Stone - Subterrean Tremors
-
Rakdos Signet -
Soulblade Djinn-
Chromatic Lantern (a good card indeed, but with three color and a solid manabase it's not that necessary I think)
And add :
-
Jori En, Ruin Diver -
Opt (Filter, that's always good. Or Serum Vision if you like but the sorcery speed is more prohibitive )
-
Thought Scour ( Lets you put two cards in your graveyard, almost like drawing 3, at instant speed )
-
Ruby Medallion and / or
Sapphire MedallionAnd that's it ! Hope that helped, and have a nice day
