I really feel like I could write an entire dissertation on this deck, so I'll try to make a little article about it:

I have a knack for bad tribes; I don't know why and I should probably seek help. I've built Ishkanah Spider Tribal twice now and in this second iteration I think I've nailed what the deck and tribe seek to do. When you're working with a gimped tribe the key is to work around their individual strengths while also establishing a grind/win condition. In spiders, it is a joint synergy between filling my graveyard (aristocrats and also delirium for Ishkanah), getting a ton of mana (to cast spiders and activate Ishkanah), and to leverage the big-butt nature of spiders to hold off attackers until I can establish a game state where I can acomplish this.

Dwarves has nothing close to that.

Magda is an INSANE card by herself, if she supported any tribe other than Dwarves she'd likely be insane. Dwarves' archetypes are pretty split between artifacts/vehicles, low-cost creatures, and land destruction. So the deck operates like an aggro deck, with the only real aggro card being Magda herself, and the creatures have no benefit in being aggressive apart from triggering from Magda. The land destruction aspect doesn't work apart from giving the Dwarves a way to tap for treasure from Magda other than attacking, which is a bad idea. Vehicles are strong in the deck simply because the mechanic of crewing allows Magda to be at its best, but this feels disassociated from what all of Dwarves want to do, now their tribal synergy is that Magda cares about their creature type and not much else. Add to this that Magda also wants to play HUGELY expensive artifacts/dragons in a deck that is simultaneously trying to be low-to-the-ground so you can pump out treasures as quickly as possible and you have an absolute trap of a deck.

You're better off playing Mono-Red Dragons, as each play you make should be a haymaker, and you'll likely play them almost as quickly as a Magda deck will.
