if i use primitive instinct to use chi disruptor as a block and then us chi disruptors ability to turn it into a reversal and hit with it, does chi disruptor still get removed from play or can it go to my momentum?

Thats a good question. It will come down to whether Chi Disrupter is still counted as a block when you play it as a reversal. If it is still considered a block, then it gets RFGed. If it stops being a block, then becomes a reversal when you R with it, it should not be RFGed. Currently, there is no precedent for a card staying in the card pool but being replayed as something.

When a card changes zone it loses memory of effects like PI unless the effect specifically states otherwise. CD moves to the Transitional zone so will not be RFGed whether you succeed or fail in playing it as a reversal.
