Binge and Purge

Step 1: Binge - Get your ridiculous card draw and hand size machine running.

Step 1.5: Regret - Regret the decisions you've made that have brought to the point of having a 20 card hand size and no way to pay for anything you have.

Step 2: Purge - Install all the viruses. Mill the shit of the corp. Don't even run. Not worth your clicks.

Rinse and repeat until the corp has no more cards to pull.

With 23 virus cards in your deck, you should be able to mill enough cards to deck most corps.
