Loki isn't a horrible champ; he's just not as good as the other champs available. His SP1 is useful and can be kind of fun, especially when fighting against a champ who spams buffs.
If you have better champs available, Loki probably isn't worth ranking up.
I certainly wouldn't call him trash. He's one of the few counters for classic Ultron in 5.4.6. and as mentioned the Hela synergy is good. He's by no means great, but he can be effective in the right situation. That being said, he was my second 5*, I have him thrice duped and never took him above r3.

I'd put him soundly in the bottom tier just above Groot
If you need a sp1 buff steal, go for rogue, she prevents the opponent from regaining the buff as long as you have it yourself

Have u seen him with the Hela synergy ?
Exactly my point haha. With Hela synergy he's even better. Loki is VERY underrated... A buff wouldn't hurt but he's still a very underrated champ 😉
