    • (PC Only): Press F12 to open the DevTools window => Navigate to the Console tab in the window => Paste the export code => Hit Enter
    • OR (Other platforms/PC): In the address bar of the current tab remove the URL and type "javascript:" without the quotations then paste the export code, then if you're on mobile look for the *globe* icon and tap on it to run the code (Chrome only), for PC users just hit enter.

Notes & Combos

Slightly different approach than my previous build, This time I'm using less mathmech names and using the spirit engine instead, I think this is more optimal until diameter gets unlimited.

Removed talents to keep the deck at a clean 40 so I have higher odds of drawing the good cards like Maxx C, Circular, Ash, Called by, and crossout.

I still believe update jammer is useless, and 2nd splash is very handy especially in long duels or when you get nibbed at a critical moment.
