Grey Nymph becomes malignant cell

[dragonsdemesne]

Playing against rob77dp in league, I had a grey nymph in play.  I used its aflatoxin on itself; rob used eternity to rewind it.  I replayed the nymph next turn, and when it attacked, it turned into a malignant cell.  I remember seeing someone mention this in relation to chimera, but not in this particular case.  Rob said it looked like I played a cell straight from my hand.  I'm not sure if it did 8 damage or 1 the first turn, but it behaved as a cell after that, multiplying and doing 1 damage and so on like a cell does.

I'm pretty sure this happens with any creature removed by any non-lethal CC (usually RT). The next creature played in that slot will immediately turn into a cell (hence Chimera being one of the most noticeable).

So this is what happened.

Turn 1: I afla'ed myself and played RT on it.

Spoiler for Hidden:

Turn 2: I didn't have quanta to play the grey nymph. Nothing abnormal happened.

Turn 3: I played the grey nymph and waited; nothing abnormal happened; it attacked like normal.

Turn 4: I decided to alfa myself again. It INSTANTLY turned (without even attacking) into a malignant cell.

Spoiler for Hidden:

This was done in normal game, not trainer.

I can confirm this as well, I just tested this several times.
