Tribute 1 Insect-Type Monster on your side of the field. Special Summon 2 "Army Ant Tokens" (Insect-Type/EARTH/Level 4/ATK 500/DEF 1200) on your side of the field. The tokens cannot be used as a Tribute for a Tribute Summon.
If i remember correctly and how it goes, pinch hopper being sent to the graveyard has to be the last thing to happen, since the ant tokens bieng summoned is the last thing to happen Pinch Hopper can't use its effect
This card is absolutely amazing when comboed with atmosphere. Summon an insect, use Multiplication of Insects to tribute it, banish all three to special summon atmosphere.
