This loop transforms any initial instance of lifegain into a self-sustaining engine of growth, utilizing Archangel of Thune as the primary catalyst that distributes +1/+1 counters across your entire board. That burst of counters immediately provokes Invisible Woman, Sue Storm into generating a 0/4 Wall token, whose entry to the battlefield is carefully watched by Elas il-Kor, Sadistic Pilgrim to instantly return the favor with a fresh increment of life. Because that new lifegain naturally feeds right back into Archangel of Thune, the entire process cascades endlessly to flood the board with tokens and infinitely large creatures.
