He has to have a life lead & 100 meter to RC GF twice and then not mess up the gimmick for 30s by accidentally grabbing you or letting you touch the ground.
It's pretty rare to be in a situation where:
Tager has 100 meter +
a life lead +
hitting you with a combo into this +
it actually matters that Tager is time-gimmicking you
Generally Tager could just kill you at that point or the round will be pretty close to over anyway. You'll notice that Litchi does indeed have pretty damn low HP when this gimmick actually comes into play. Tager could've just killed Litchi with the combo he confirmed in the vid, unless they hella gimped his OD MTW>TB damage in CPE. In CP Tager gets 5k+ even on a 5A hit with OD MTW>TB
I'm not saying timer scams are great, cuz they aren't, but if you allow Tager to get 100 meter and then also let him hit combo you into this you probably don't deserve the round anyway. The gimmick isn't infinite either it actually wouldn't have lasted much longer than it lasts in that video because magnetism would've worn off from that last GF.
tldr: you should be more mad about his new Sledge I can't wait to kill everyone with it.
