If this card in its owner's possession is destroyed by an opponent's card: You can target 1 other Dinosaur monster and/or 1 Rock monster in your GY
Black would be my second pick: Necropotence and Necrologia are huge burst draw, but theres also Ambitions Cost / Ancient Craving, then some other stuff like Greed
In exchange, you get to do 80 damage to every Pokemon on the field with Poke Powers
Since it's no longer a creature, the Angel is removed from combat, so it's no longer attacking (and thus will not deal any damage in combat)
A deck that focuses on ramping up mana quickly, such as a green ramp deck, would benefit from using Explore as it allows for playing an additional land and drawing a card in the same turn, providing both card advantage and mana acceleration
Thats about as close as fans will ever get to a crossover other than unofficial Pokemon cards made by fans.
