You have a little bit of Everything when it comes to AoE, and I even add in Big Ol' Whelp and Squallhunter just for the sake of 1 Lightning Breath.
Speaking of Squallhunter; This is Ras Frostwhisper‘s Mount and Companion as they work together and deal 3 Damage to all Enemies, and with Rune Dagger, (if I’m reading it correctly) Ras could deal even 4 Damage to all enemies; so the Theory is that It’s a Midrange Deck, That scares even Midrange Decks. Guardian Augmerchant is there to protect your most important guys. Even Totem Goliath has a Spell Damage Totem when it dies, and it also has a second “Taunt”, which would be both Stoneskin and Wrath of Air Totem. I considered getting some Totem Synergy Cards, but I tried. It was too many cards to put in, so I had to scrap the idea and changed it to full-on Transforming.
Rouge’s Bamboozle was a success, so I figured that so can Explosive Evolution could do the same.
(Oh, and Lightning Bolt is for Execution (Dealing 4-6 Damage on the Opponent), but you can replace it for something else if you want.
