This deck pursues tenets of three common archetypes/plans without diluting any of them too much: Ramp, Midrange Beatdown, and Midrange Control. Normally this would be a terrible idea, but it's possible because of Glittering Wish, Garruk Wildspeaker, Xenagos, the Reveler, and Primeval Titan's land tutor ability.
Plan 1: Ramp
This plan seeks to go over the top of your opponent by ramping into Primeval Titan using Birds of Paradise, Noble Hierarch, Garruk Wildspeaker's +1 ability, and Xenagos, the Reveler's +1 ability. It uses Glittering Wish for Dragonlord Atarka, Sigarda, Host of Herons, and
Realm Razer
(see plan 3) as finishers 5-8. It also uses Primeval Titan's land search for Raging Ravine (possibly substituted for Treetop Village), Kessig Wolf Run, and Gavony Township (see plan 2) as even more finishers. Courser of Kruphix adds a lot to this plan by helping you make land drops. The combination of Primeval Titan, Glittering Wish, and Kessig Wolf Run give you a similar number of finishers as Tron. This is your main plan.
Plan 2: Midrange Beatdown
This plan seeks to fill the board with a mixture of creatures that are aggressive and strong in combat, including Tarmogoyf, Courser of Kruphix (adds enchantment for Tarmogoyf!), Garruk Wildspeaker's beat tokens, Xenagos, the Reveler's hasty satyr tokens - plus either Gavony Township or Garruk Wildspeaker's overrun ability (which make your mana dorks threats). This is the weaker plan but frequently the one that gives you the kill. This is because this plan happens naturally as you try to put together the ramp pieces or your opponent deals with components of it (i.e. kills Primeval Titan).
Plan 3: Midrange Control
The plan seeks to interact with your opponent to shut down their plan and then kill them with one of the other plans. It uses Lightning Bolt, Path to Exile, Courser of Kruphix (blocking + card advantage), Ghost Quarter, and Glittering Wish for hateful bullets and some catch-all interaction. Having access to 4 copies of the following cards straight up demolishes certain decks while providing circumstantial aid against others:
a) Fracturing Gust: Hoses Affinity
b) Firespout: Hoses Aggro
c) Wheel of Sun and Moon: Hoses Abzan Coco game 1 as well as Dredge and Goryo's Vengeance
d)
Meddling Mage
: Hoses combo decks without bolt.
e)
Realm Razer
: Hoses Scapeshift, Tron, GR Valakut, and sometimes any other deck...
f) Sigarda, Host of Herons: Hoses fair decks like Grixis, Jund, and Abzan.
g) Alive / Well or Heros Reunion: Hose burn and zoo, but those aren't bad match-ups so I'm running Kitchen Finks for reasons described in the sideboard notes.
Glittering Wish also gives you access to some more uniformly useful interaction, mainly Detention Sphere and Dromoka's Command.
Sideboard Notes
Testing is showing that there are only 5-10 multi-colored hosers that legitimately win games for you once you a) factor in that you have to pay 2 mana to Glittering Wish on top of the bullet's mana cost and b) factor in that your opponent will know it's coming. Additionally, sometimes you will have 4 dead cards in a match-up. Usually this is Lightning Bolt but sometimes Path to Exile. This fact incentivizes you to include some Glittering Wish targets that you won't wish for a lot but are fine bringing into your maindeck post board. Right now these are Loxodon Smighter and Kitchen Finks, but depending on the match-up, could include cards like Detention Sphere or Dromoka's Command.
I haven't tested all of the match-ups yet but I know there are going to be some where you're a dog and there's no suitable Glittering Wish target. I'm reserving 4-5 sideboard slots for these match-ups. Right now my maybeboard is set up such that:
a) 1x cards are potential wishboard inclusionsb) 2x cards are potential mono-colored sideboard inclusionsc) 4x cards are potential substitutes for Courser of Kruphix (4 mainboard slots could be a mix of these 3).
