My MWL-legal deck I took to the Reading (UK) Store Championships.
Out of 5 rounds of Swiss, this deck won 3 out of 5 games it played.
Usual Blue Sun: Powering the Future antics with Oversight AI with Curtain Wall and Orion backed up by possibly excessive levels of meat damage.
False Lead and Enhanced Login Protocol to cause tags from passing Data Raven (or a foolish Account Siphon and such) to stick, and Scorched Earth and Punitive Counterstrike to punish anyone who ran or stole an agenda.
The quirky splash is on Psychic Field, which really is this deck's MVP in many a game I have played. An unaware Runner often will slam into it believing it to be an Project Atlas or other agendas; losing thier hand of toys if they fail the Psi-game, and making the SEA-Scorch-Scorch more likely to outright kill them. Or, alternatively, deployed behind a Data Raven; Dedicated Response Team to finish them off when they complete thier run.
If the Runner fails to fall for the trap, you can use Blue Suns ability to bring it back to hand and play the mindgames all over again...
Ultimately on the day, the deck did not fair well against the many Anarch decks due to excessive milling of R&D/HQ, and thus most of the fiery goodness the deck packs was lost.
Improvements would be to add in a Jackson Howard or two to help restore some of the decks capabilities against destruction Anarchs, possibly ditching the Excalibur (who only exists for annoyance reasons and as a funny subroutine to pull in with Orion) for some more ETR/OAI-able ICE, and possibly shrink the deck down to a more palatable size (... I like 54 size Corp Decks!).
