This clever loop turns Necrotic Ooze into a one-frog engine of pure arcane power by stitching together activated abilities from the graveyard. With Wizard Class leveled up to grant its wondrous card-drawing triggers, tapping the Ooze via Arcanis the Omnipotent's ability draws a trio of cards—which in turn prompts Wizard Class to beef up the Ooze with +1/+1 counters. You can then instantly erase those newly acquired counters by activating Devoted Druid's untap ability, wiping the slate clean so the Ooze can tap and draw all over again.
