I hate this so much, theres no skill, no setup and no counterplay as some others will tell you.
Its the most simple, braindead combo someone can pull with no serious downsides, I cant tell you how many times i've had a round 2-0 and get reverse 3-0'ed because they have the cards, card profain for a second round and then im stacked under on cards for the final round (this has happend alot sadly ;-;).
On a less salt laden reaction, I gotta be real this is something that is plaguing the higher tiers of ranked, it isnt hard for a stevie to mow you down before you can even play poison or a duck anderson slooowly riddle your ice block while you just watch him do it, I've adopted all the counters but bombs dont go through it anymore, karrotov doesnt pass through the wall either even when placed directly on top of it and the only realistic thing to do when its played is use poison bullets and hope they dont have cards to heal, theres no counter play, no interesting hide and seek dynamic and it overall impacts the games balance gigantically because to beat a 5 or 4 card combo you need to put 2 for karrotov or 2 for poison bullets, poison B. is a good card but karrotov is a waste and absolutely over valued for what it does, please for the love of all that is friendly, fix/nerf this please!
(I understand this was posted before but we've gone a good amount of patches with no mention to it, so I will once again start this push to not deal with it.)
