Ekomind sets the base memory limit for the Runner, which can then be further increased or decreased by other modifiers. If the Runner plays Levy AR Lab Access, the number of cards in his/her grip is temporarily 0, and thus his/her base memory limit is also 0.:Ruling
1. Ekomind + CyberSolutions Mem Chip (+2mu) Does your memory =cards +2mu or does the text on ekomind decrease the limit to cards in hand.
2. So if i Levy AR Lab Access with above setup and shuffle all cards back in. Then draw 5. My memory drops too 2 or zero then back to 5 or 7 Ekomind sets the base from which you increase and decrease memory. So in that situation, you would have cards + 2, or in the second example 2 and then 7.
