Let me see..... You play pest, then play Eclipse. Now you got a 2/4 creature, you antimatter it, now you have -2/4? Explode the eclipse, now you have a -4/3 creature? You antimatter it back, now you have the pest at 4/3 stat. Now you play another eclipse, and you get a 6/4 creature and repeat what you did before. Is that right? I'm not really sure, I usually don't bother with trainer so I'm just guessing.
