Because of his effect Simorgh, Bird of Ancestry is treated as a Normal monster while in your hand, making him the only monster capable of utilizing the effect of Wind Effigy. And they synergize quite well because with a WIND monster as the only tribute Simorgh, Bird of Ancestry's removal effect will trigger.
Why don’t they just extend this effect to Harpies’ Pet Dragon? In the TCG or this game lol
I wonder why they never printed any Level 7 or higher WIND Normal monsters even after being clearly fully aware that they had to slap that weird effect on Simorgh Bird of Ancestry just to make this card usable.....
