My Agent Venom handles him and the other speeds pretty nicely. Best to have a buffer character that can kill a few seconds in the lead spot so he can go right into iFrames when he starts, so he doesn't get one-shot.
Also Jean can take him down, but you'll probably lose a life in the process.
T3 cap with CtpR can kill him "only" when you play manually & interrupt him while he uses his defence down skill. That particular skill & constant healing makes him able to stack & deal tremendous dmg.
If you want to win t3 dp vs t3 dp then prioritize on his defence down skill & try to stack them. In addition try to interrupts his skills amap.
