Re: can a reincarnation reincarnate into a reincarnation

I would say yes it could change into a +1/+1 version of itself, but no I don't believe that you would get cumulative effect like the clique peas.
There's a screenshot in the thread of sharing your screenshots that shows a seedling turning into a seedling...captain cucumber can conjure another copy of himself, so I don't have any reason to believe that it's not possible.
