Notes & Combos
Stein FTK except Hugin baits a good chunk of handtraps and also runick spells occasionally break boards or keep you in the game for an eventual "FTK".
Top Secret Packs used

https://www.reddit.com/r/masterduel/comments/zvvy1v/dont_like_playing_against_a_boring_stun_deck_now/ This is a recording of the standard combo line!
When you open Stein, you skip a bunch of steps, and make Power Tool with Hugin plus Theseus. When you open only Recycler, you do the Scraptor line, except Wyvern just directly specials Scraptor (instead of Golem reviving it), so you need an extra Runick spell to activate so the tuner Stein summons (Theseus) can be paired with another body (Hugin) to make Power Tool.
(This isn't so much to do with the combo but, when possible you're supposed to discard a Runick spell for Hugin to avoid telegraphing what you play - and also Charging Cell should be activated elsewhere to play around Tiamaton 🙂)
