CotT: Prof-X vs. Elektra
A tale of pure RNG.
First time though, a turn or 2 after I went invisible she destroyed the tile with a match 4 and I was never able to get enough to go invisible again. Despite being lucky enough to match her Red trap once, I could not find / match the 2nd one she got out and she eventually whittled me to death in a long battle.
Second time though, I went invisible early and remained so for 90% of the match because it was well placed on a side and I ended up winning after losing barely any health since while I was invisible I was immune to her Black and Red trap damage.
What's funny is the in both matches I got a match-5 early on for tons of damage and then another one mid match and in both battles the 2nd one happened a turn or so after her Shadow Step had just been cast so it did nothing. Essentially I had 2 identical battles and the luck of the invisible tile placement meant a loss vs winning with essentially 0 health lost.
