The 99% Experience

This deck forces the corp to pay a premium on ice, using Xanadu and Rook. Once up, ice can be dropped again using Parasite and Cresentus. Knight makes a solid early breaker, weak only to Swordsman (answered by Mimic or a good Parasiting). The deck is slowed by corp playera trashing ice with installed Cassia on it. Try to keep Knight on more costly pieces the corp has paid dearly to res, and use Crypsis, Mimic and Yog to handle cheaper ice. All else fails, Clone Chip and Retrieval Run can bring those key programs back - including Parasite and Cresentus, if needed.
