So I thought you had to meat the or beat the strength of the card you are incountering? If I use wyrm with Mimic I have to meat the strength of the card first before I go to the subroutines. Yes I bring the strength down with Wyrm, does it stay that way when I use Mimic or does it go back to its orginal strength when I encounter it with mimic. I can't find any where in the rules that state I can use 2 different cards or that if you bring the strength down it stays the same through out. Because there are cards out there that say when you increase the strength it stays that way for the run. ie. Battering Ram " +1 strength for the remainder of this run" you would think it would say that on wyrm if that is that case.
You have misunderstood how a run works. You, the runner, make the run. So you, the runner, encounter a piece of ice. Then you can use all the tools at your disposal to deal with that piece of ice. You can use multiple cards to interact with the piece of ice you are encountering. But you must follow the rule that an icebreaker can only directly interact with ice if the icebreaker's strength matches the strength of the ice. The strength requirement must be met for each icebreaker individually.
