NOW FOR THE REALLY GOOD NEWS
LEX HAS AN INFINITEEEEEEEEE.
Ok, so
rev0lver found a reset where if you have shields, you can use the meterburn lance blast and MB probes to get a guaranteed full combo. By having shields, its a guaranteed reset, because if they try to hit you out of it, they'll just hit your shields and you can react by letting go of the lance blast- and you can get a full combo off even a level 2 upwards lance blast. So even multihit wakeups can get stuffed by this if the Lex player can react at least before the second hit. I set a Deathstroke AI to wakeup randomly and found I could react to both Sword Flip and sword Spin fast enough so they would take away my shields, but eat the lance blast before the second hit connected.
So the issue is this would be hard to set up. Because you need shields and MB probes out.
So I found a way to get shields mid-combo, end with MB probes into this setup, and then go into a full combo which would ALSO get shields mid-combo, so this can be looped INFINITELY! Well, so long as you have a bar of meter, but what I also found is this infinite loop uses moves that build a TON OF METER. You gain almost a half bar for every bar you spend. And if you run out, you can still use regular probes and go for a 50/50 meterless reset using b2 xx upward lance blast or b1 xx upward lance blast.
This is ONLY possible on Fortress of Solitude using the teleporter interactible on the far right.
Here's how it goes, I will use asterisks for footnotes because it gets complex.
f2, b2, 11, 11, u3 xx Teleporter, Close Gravity Mine, 1 xx Trait* xx Forward Dash, u3 xx MB Probes**, Level 3 Upward Lance Blast***, 11, 11, Teleporter****, Close Gravity Mine, 1 xx Trait***** xx Forward Dash, u3 xx MB Probes, Level 3 Upward Lance Blast, 11, 11, Teleporter (AND REPEAT)
* Only charge trait to LEVEL 1. Do not charge to level 2- so release the trait button the second you reach level 1. By only traiting up to level 1, you ensure that trait will wear off immediately after your Level 3 Upward Lance Blast, and will be back and ready to use by the next time you need to do it.
For the '1 xx Trait' the '1' should hit the enemy BEFORE they land in the mine.
** After the forward dash, DO NOT do u3 xx MB Probes immediately. Wait for Lex to come fully out of his dash animation, and then do the u3. You should have no problem with this as the timing is lenient so long as you where fast on the trait-dash-cancel. The reason you don't want to be too quick to do the u3 is you want to let your shields wear out a little. I found if I did this too fast, I wouldn't always have shields back in time to do the quick 1 xx Trait I needed to in order to continue indefinitely
*** Remember, UPWARDS lance blast. This comes out faster than the regular version, and is MUCH easier to combo off of. If you see the opponent do a wakeup, or any regular attack, make sure you release the lance blast- as the the level 2 lance blast will still allow you to get the full combo you need, and the MB probes will help juggle them afterwards.
**** Do not CANCEL into the teleporter from the 11 before it. Your shields still need that extra fraction of a second before they are available again, and you get this by hitting the interactible teleporter while the enemy is still in the air after the first 11, but not as a direct cancel. This ensures your shields will be available JUST as Lex is ready to cancel 1 xx Trait after the close gravity mine he throws out after the enemy emerges from the teleporter.
