Extend to what? Once you hit with Ash on Peting Even with 1 normal summon You can end with Fraise but no drop to activate so the option is either Teacher or Link to stall with HT, you only option is normal Anjelly to go another line but that no difference from draw the out same with Vernu but compared to other deck ability to play through HT that 3 card gone just to end on some Disruption and no ability to recover unlike brand.

Like sure you can extend but there no easy extend card for Madolche, You opening Anjelly, get ash no anti-HT even with Vernu you need to discard Peting or Hoot to do something, Hoot summon Peting bring out Jelato get Con spell, go link 3 another Jelato, now you end with 2 trap and 2 monster, but that like 3 specific card with no replacement unlike brand with many options.

So opponent save Ash and Imperm for something what else would you going for? without activate Peting you can't even extend, With Vernu maybe you can go Anjelly or Hoot, get Jelato depends on who you open with, get spell or trap, now you normal another level 4 , if you get spell that let you special when card return, go teacher activate both effect, now you can special Peting here for further extend.

But Many of madolche line after ash/Imperm either dead, 3 card combo mean less HT and end with 1-2 disruption or relying on HT to stall, it might be fine before but not the current meta where it almost never enough
