Unstable Magus Herald

Survive until turn 3/4 against Stonescar and then Go Off™ using Mentors to power up heralds if the board is slow, or playing multiple heralds using twinning + another spell to activate effect, and then using the next turn to turn one of them into a 7 mana cost unit. There are a few bad results of this such as flight commander but most of them win the game outright.

Aviasaur is included for use on Magus for a powerful turn 5 after the initial combo with Heralds allowing you to play a Magus and keep a backlash against Harsh Rule, or to Magus and Unstable Form the Magus to avoid his downside or the Dragon if you want the 7 manacost unit and have a buffed Magus.

Saving spells for combo on turn 3/4 is encouraged.

Use Mentors to powerup 4 costs including Herald, and as protection against not drawing unstable.

Unstable on Marisen's can get Idol of Destran rarely for a brick but is usually worth the risk due to the possibility of a powerful 5 drop and the Marisen's unit on turn 5.

Levitate for pop of aegis/combo with Northwind and extra card draw.

Marisen's and Elysian Pathfinder are replacable as there is enough combo in the deck to jam titans in if wanted.
