Do you mean Shadow Ryder Calyrex? Accelerate the energy, the same accelerated energy boost the attack so its quite damage booster, just change the energy switcher for Draw Power and its pretty much the same thing you mentioned, at least these Monsters are a little bit more hard to get in the field and just one, while Calyrex can be an entire army of 4 in the field
Well no, not really, i just gave these abilities as an example because i was shocked by the fact that a single Pokemon has 3 abilities, but i guess calyrex is similar in one way or another lol
