These include creatures that generate additional creature tokens (Blade Splicer, Darksteel Splicer, Defiler of Faith, Phyrexian Triniform, Ria Ivor), buff/anthem effects (Defiler of Flesh, Grafted Butcher), Incubate (Essence of Orthodoxy, Progenitor Exarch), reanimate (Phyrexian Delver, Sheoldred), removal (Sheoldred), drain (Elas Il-Kor), and many more
