This delightful loop relies on casting Sensei's Divining Top directly from the top of your library, a feat made possible by Falco Spara, Pactweaver's static ability allowing you to play topdecked spells using creature counters as payment. To make this economically viable, Semblance Anvil reduces the artifact's mana cost down to zero, meaning you pay entirely with counters instead of mana. Every time Sensei's Divining Top re-enters the battlefield, Yotian Dissident's triggered ability steps in to replace the spent counter by bestowing a fresh +1/+1 counter onto a creature. You can simply tap Sensei's Divining Top to draw a card and put itself back on top of your library, restarting the cycle to draw your entire deck while generating endless artifact entry triggers.
