First draft, untuned, untested, of my ideas on Thunderkin Awakener in standard. Started as a Cavalcade variation utilizing Mask of Immolation with awakener for stuff, but the idea changed while I wrote it out. Merchant is listed in instant/sorcery because it should always be cast for it's adventure. Thoughts, opinions, criticism, improvements, playtesting results, insults, etc... all welcome!
