Imo he is worth the profile picture alone, if you get a good one out of the RNG
I realize that time attack legends runs are ending this month, but he automatically makes you get a legends title for now if u have him at 5/65.
he seems ok as a trophy and such long process and rng to get him, one expects lot more from him , at the very least new animations...!! he's supposed to be mascot guy for the game, he's been there since initial days, he carrys freakin two katans, guns, has magic pink bag that can carry infinite stuff, has death as lover and all we get is 4 very underwhelming versions of him!! this just makes the game look bad that same character is reskinned over and over with no new animations, no meaningful utility or ability or even straight up damage!!
As a free to play, getting crazy lucky, then for sure yes. Depends on how much you have to whale out for him, but in comparison to spending units for gold, completing an easy quest or a few incursions for him, plus a ton of units was definitely worth it for me. I had some mutant gems and he is quite a fun champ to play, so I took him to R4. His synergies for me seem to be the weakest point (he doesn’t have a single synergy that does anything other than give him a higher chance at certain cards, nothing to boost base stats, or to boost any other champs).
