Atman: Meta Defining Card
At 3+ install cost, Atman can be tailor made to target all instances of ice that share a particular level of strength. It is however inflexibly unable to target ice that is higher OR LOWER than this tailor setting. It's common for runners using Atman to install several copies of it forcing Corp players to diversify the strength of their ices when building their decks.
Atman is one of the few ice breakers that actually combos with itself. Runners makes sense to have more than one copies installed simultaneously. This strategy allows the runner to target multiple strength levels of ice
Plugging holes: with a suite of Atmans installed at different strengths, Datasucker can potentially be used to fill in the cracks. Additionally for Anarch, Mimic, Yog.0 & D4v1d could add more efficiency to such a strategy.
Atman can be installed in the early game to deal with a specific hole in the runners deck, then trashed to make room for other programs and then brought back (to deal with an end-game headache) from the heap with recurring cards like Retrieval Run, Clone Chip, Déjà Vu, Test Run, Scavenge or Trope but watch out for Blacklist or Chronos Project!
Similar to Femme Fatale, the runner has lots of control in targeting ice, being able to custom create an instance ofAtman to deal efficiently with a specific level of ice is why Atman has been so popular in the past.
Big taxing ice like Orion, Wotan etc can be much more efficiently managed with Atman targeting it at significant savings especially if the ice is guarding a server like R&D or HQ where the runner may wish to run repeatedly.
As an AI ice breaker, Atman can break nearly every ice out there
Atman's inflexibility once installed means runner will most likely still need a full suite of ice breakers
Advance-able or otherwise adjustable strength ice such as Shadow, NEXT Bronze, Quicksand, Resistor, IQ, Fire Wall, Hadrian's Wall, Ice Wall can give a headache to any runner relying specifically on #atman as their AI of choice.
Other strength adjusting cards such as: IT Department, Lag Time, Experiential Data, Encrypted Portals Improved Tracers can throw off a very carefully tailored Atman
Can be an interesting Shaper auxiliary ice breaker and possibly cheaper to install & certainly cheaper to use in many cases compared to others. It's inflexibility however makes Atman extra challenging to pilot. It's cons are pretty tough to overcome which is probably why this card hasn't been reviewed up until now.
--It just saddens me when I see cards with no reviews. If you appreciated this review, please give a heart and I'll be encouraged to write more.
