Forum:Honest to god question about spell counters

Ok me and my frineds have been aruguing about this since god knows when so here is my question if a card like arcanite magician/assault mode (amam) is summoned and u activate his 2nd effect and remove his 2 spell counters from when hes summoned and then u activate like for example terraforming would amam gain a spell counter even though on the card it doesnt say he gains spell counters every time a spell card is activated
