This intricate loop transforms a humble mana dork into an engine for boundless growth by letting counter-doubling effects outpace the drawback of self-inflicted harm. Devoted Druid normally generates green mana at the cost of -1/-1 counters, but with Leyline of Abundance doubling its mana output, each tap yields massive green reserves while cycling the druid upright. To counteract the shrinking stat-line, Michelangelo, Weirdness to 11 and a fully leveled Innkeeper's Talent work in tandem to flood your board with amplified +1/+1 counters. Because Innkeeper's Talent doubles your counter additions and Michelangelo adds an extra one on top, the massive mana injections funded by Leyline of Abundance's activated ability permanently pump your entire team beyond recognition instead of letting the druid whither away.
