This card is insanely powerful and flexible in any virus wielding deck. 1 click and 0 creds for 2 virus counters? That's nuts. It's kind of crazy that it doesn't see more use. Don't believe me? Prepare to be SURGED.
Parasite taking too long to kill those pesky Tollbooths? SURGE IT! If it doesn't kill it out right, it's at least Yoggable the turn after you Parasite it. Or, just outright kill any <=3 str ice. That's value, mofo.
Speaking of Noise, how about Gravedigger? One measly asset trash and you can mill 3 cards off the top of R&D! Not to mention the one you milled by installing Gravedigger.
Wanna slow the Corp down and force a purge? Throw down a Chakana, run R&D and then SURGE!! Watch them cry as their Astrotrains go flying off the rails.
Feeling really batshit crazy? Why don't you finally make that Deep Thought deck you always wanted and SURGIFICATE IT!!! Scope out R&D and snipe them Agendas.
Don't even get me started on Hivemind...
The worst thing you can say about Surge is that it takes up 3 deck slots. But you don't really care do you? No. You don't.
Get out there and SURGE.
