This is pretty obvious but when you get a new Metal Change Core it is very very easy to launch it in endurance mode. After about 40 battles it wears down and gets harder to launch in endurance mode. This can be good and bad. With a more worn down tip you get a lot of attack. So here is the situation.

Stadium- Tornado Balance
Oppents Blade- Samurai Changer MS, starts battle with endurance tip
Oppent Skill Level- 10/10
Blades you can use-

DEMS In Mint Condition

DEMS With Worn Tip

Which one would you use?

DEMS mint, trying to one hit K.O. is what I would try first, but SCMS is heavy, so no. I would launche it in endurance mode, and I'm sure when ti is hit it will go to attack, and SCMS will loose endurance and spin rate, and then dEMS would come in. Other wise, gah...

DEMS slightly worn tip, launch in endurance mode at the beginning of the match so it can stay in the center for a good 20 seconds, then it will start to slowly spin outward, causing a hard collision with SCMS, and possibly a one hit KO.

DEMS Mint tip.
Because DEMS would spin in the center for 20 or 30 seconds swapping hits with Samurai Changer.Then Samurai Changer MS would more likely hit DEMS out of the center and send it into attack modeand then KO Samurai Changer MS

You wouldn't have enough endurance for SCMS =/...... Your would loose, with mint you are in endurance mode and then when it is worn out from switching and attacking, you hit him with attacks because he will hit you into attack, or you just outspin SCMS..

Show me a video and I will believe you.

I can't show you a video, but can you show yourself? You have SCMS? Then get a new DEMS, and make your old one verse SCMS five times, and your new one verse it five times.
