Notes & Combos
It took some tweaking to get this to work as is. Mathmechs need the Xyz's to be worth splashing.
The strategy is pretty straightforward for @Ignister decks before Mathmechs and Firewall Singularity (may find a way in later) entered the game: going first, set up The Arrival and enough shenanigans to go into AccessJammer OTK on turn 3. If going second, go for AccessJammer OTK and only involve the Arrival as a backup plan.
