We remove everything the opponent plays, and then beat them down with huge dragons.
Dragon Forge can be tutored with
Garden of Omens to grab you some very powerful options:
Magebreaker to remove problematic spells like
Worthy Cause and
Shen-Ra Speaks.
Thunderstrike Dragon to reliably draw two big dragons without having to include more than 1 maindeck copy.
Karvet, Solar Dragon if you need a lifesteal blocker, or don't have PPP for Thunderstrike.
Clutch of Talons as a win condition that can also turn a merchant into a big flier in emergencies.
You can recur all of these things with
Voprex's Choice, which can also be tutored for via Garden and/or Re-read. Tutoring into other tutors is made feasible because of Garden's cost reduction.
Blitrok, Linrei's Listener is very powerful. Primal has a lot of strong attachments, and the ping effect makes it very easy to activate the mastery, invoking a second time and becoming a 4/6.
Den of Ordeals comes out a turn faster than Office, and will generally win the game if it goes off. If it doesn't go off, you will often kill something and guarantee gas for the next 10 turns, which is often enough to close out the game.
