Professor of Alchemy
"Alchemy Beast Tokens" can attack directly. Once per turn, during your Main Phase, you can banish 1 Level 4 or lower monster from your hand or face-up field, to Special Summon 1 "Alchemy Beast Token" (Rock/Level 3/ATK 500/DEF 500), with the same Attribute as the banished monster. It cannot be Tributed, except for the face-up Tribute Summon of "Golden Homunculus".
