An interesting card with a payoff limited by what ice and upgrades you use.

.

Eliza is situational due to competition from Melange Mining Corp. .But what about high cost cards like Hadrian's Wall, Wotan , SanSan City Grid (if an opportunity to use the interaction to score an agenda presents itself) or Wall of Thorns? Being able to deploy Janus 1.0 in spite of economy lag can be a daunting call.

Eliza costs 4 to rez and rezzes something else for 3 clicks. She takes a fair lump of credits to trash to compensate.

Melange only costs 1 to rez and gives 7 credits for those same 3 clicks, giving an effective net yield of 6 credits the turn it's rezzed and fired. But can be trashed on a whim and the turns spent melanging can be mitigated if you try to rez all your big ice too quickly.

.

Neither of them are cards the runner wants to particularly see for more than one turn.

Like Melange, Eliza's gravitas becomes stronger as the game goes on. But her effect is sorely wasted on anything that costs 7 or less credits to rez, as Melange is easier to get out and fulfils the requirements more easily, all the while maintaining influence neutrality, unlike Eliza.

Not for all decks but an interesting way of getting a powerful glacier out on the cheap.

The first thing that springs to mind is a certain other Bioroid barrier ice that is the same strength and has the same number of subroutines for 1 credit less (Eli 1.0).

It's easy to compare Markus to Eli but Markus's strengths as a Bioroid barrier are nuanced.

When the runner is scouting ice early game, runs 1st click and Eli pops up, they're really in no danger and can safely bounce off and react accordingly with their 2nd click. If they're scouting ice and they happen across Markus, they absolutely want to break or at the very least click the first subroutine if a barrier breaker isn't around, and clicking past subroutines is a horrendously poor use of resources early on.

The capacity to trash R&D Interface and/or Desperado rolled into a piece of ice really cannot be overlooked, especially against Criminals (I'm looking at you Gabriel Santiago). I feel the fact the Runner still chooses what gets trashed is ironically immaterial: it will slow down whatever combo they're trying to pull off and requires them to run some card-redundancy to avoid hard decisions with cards they want to stick around.

Markus cannot and will not ever replace Eli 1.0 as Haas-Bioroid's #1 cheap barrier. But he arguably supplements other ice better than Eli does for the fact Eli is a speedbump but Markus is a speedbump studded with nails that can lead to some rather sore injuries if the runner slips, depending whether Markus is leading in front of ol' Zed 1.0 or is following in the shadow of Ichi/Heimdall.

Viktor 1.0 is an excellent buddy for the fact it then requires 2 different breakers (or all of the runner's clicks) to get past the pair unscathed.
