yugioh herald cards YU-GI-OH! - of Ultimateness (MP15-EN157) - Mega Pack 2015 - 1st Edition holofoil pattern or surface detail) Herald of Pure Light |

In simpler terms: as long as, say, your Mega Charizard X EX is on the field, Oricorio can dance an extra Fire energy into play every turn

Its cannons-blazing artwork is instantly recognizable, and it was one of the first cards many players associated with raw power

In addition to the looseness of the conditions for using the effect, the fact that the activation timing is arbitrary, so you can call out the convenient monster from his deck at the convenient time, is the strongest bogus effect that you can never get with the current card

Its limited availability and consistent demand from high-end collectors place it at the top of Mega Evolution value rankings
