I mean let's be honest here, icy had a good year his improvement over his rookie year has been crazy but he's still no where near enough like other duelists like aspas , zekken, etc basically duelists that help their team to win titles, derke could be the perfect replacement considering he plays yoru, Jett and raze all pretty damn well, icy is also why G2 has to lot of times run a yoru on haven or not duelist on icebox and he isn't comfortable enough to send it in on entry in a site , G2 seems to be nearly perfect but they are missing a singular piece and I actually think that derke can be that piece by replacing icy on there , for them to make a title winning roster. But for some reason g2 don't seem to be getting rid of icy atleast of right now and are putting more trust in him growing in the future to be a highly top tier duelist
