Activate this card by targeting 1 Normal Monster in your Graveyard; Special Summon it in Defense Position. When this card leaves the field, destroy that monster. When that monster is destroyed, destroy this card.
Gemini monsters are normal monsters, unless they are normal summoned again when they are on the field, this means that Soul Resurrection can be used on all gemini monsters. Special summon Blazewing Butterfly and normal summon it again so you can special summon other gemini monsters with active effects.
Cards like Red-Eyes B. Dragon and Buster Blader are normal monsters that has multiple fusion monsters. You can fusion summon and use Soul Resurrection so you can fuse again, this can work well when you use fusion substitute monsters. This also works for gemini since Superalloy Beast Raptinus is usable with any 2 gemini monsters.
This helps a lot of deck, but it helps Harpies the most. Grab a Harpie, pop with Hunting Ground and instantly go +1. Or just grab a duck at end phase and switch it back on your turn for a huge tempo play. This card being around is also another huge incentive to play a Harpie deck because it is such a huge target for Hunting Ground. Why do we have to keep buffing the most played deck? :(
