Ice Denial

Corps want to protect their servers with ice. Here, we look them in the eyes and say "No".

The principle quite classic : we use Rook to ensure that each ice rez is horribly costly. We use Parasite with recursion to make sure ice serve only once. When R&D is open, we use Keyhole to make sure the corp never draws more ice.

Scrubbed accelerate ice melting and can kill corp current events.
