Really do not like this one today - way too gimmicky and contrived. Help with these two would be appreciated.

12 They blow up both sides — died from grenades exploding (9)
13 Box has repeat of old comic's work (7)

Thanks

Enlargers

12a Enlargers - anag 'r(ight) + l(eft)' (both sides) + ('d[ied]', from) 'grena(d)es'

13a Cartoon - 'carton', with repeat of 'o(ld)'

[Captain2]

Enlargers - Grenades less d(ied) + LR = both sides

Thank you. These solutions prove my point, really.

I don't think those two are particularly 'gimmicky' - some were I grant you that.
