Trapsin claw-claw [Medium to Very hard] - Depends of the opponents and his ability to mb lock you. A very good trapsin can be very hard to duel, you can't move at all. It's still a very fun duel. My tactic is to turn around with tele as fast as I can, trying to get corner lock. If trapper is good he will be moving 24/7, so once you get a lock with teleport, do a very small whirl then you can relock him very fast without getting stunned and do it again and again. Small whirls allow you to avoid the stun sometimes so you can tele faster after the whirl.
If you get stunned by mb and traps and the sin is close to you, try to ww in her direction, it's good for two reasons, at first you can hit before he has the time to tele (happens often cause you are desynching) or if he tele before you hit him it means you are not stunned anymore so you can lock him. If the sin is not close at all, then just wsg run out of this shit! and come back
Watch my Bvc Compilation video there is few rounds vs trapsin, it will give you a better idea.

Trapsin Maxblock [Hard to Very Hard] - Take less risks, you must hit a lot to kill, try to tri-whirls like a beast and put him in fhr/block animation.
Hybsin [Easy to Medium] - If he uses enigma and whirlwind often then just go "bvb" him, shouldn't be hard. If he plays, more like a trapsin, then play like if it was a trapsin!
If he uses bramble or w/e but not enigma, go bvb him, you should win anyway unless he got very very high damage.
