This engine turns the top of your library into an endless loop by leaning on a clever web of static support. Citanul Hierophants grants your creatures the ability to tap for green mana, allowing Traxos, Scourge of Kroog to help pay for the loop while Mm'menon, the Right Hand grants your artifacts the power to tap for blue mana and lets you look at the top of your library at any time. From there, Mm'menon, the Right Hand also enables you to cast artifact spells directly from the top, letting you replay Sensei's Divining Top after tapping it to draw a card and place itself back on library. Every time you cast that Sensei's Divining Top, Traxos, Scourge of Kroog sees a historic spell being cast and untaps itself, ready to tap for mana again and keep the cycle spinning.
