My rendition of part of this town from G3's era. The card's info says:
My Little Pony Unicornia
EARTH/Pony Building/Level 4/ATK 0/DEF 3000
This card cannot be Normal Summoned or Set. This card cannot be Special Summoned except when you control "25th Anniversary Celebration". This card cannot be destroyed by battle. Once per turn, if this face-up Attack Position card battles, you can have it lose 1000 DEF and make the battle damage from that battle 0.
