My thoughts about this card...
In many ways, super rod is better, due to it being an item and not a supporter. In such, you can use the rod in conjunction with a draw supporter to get back the cards you need from the discard to play right away. That suits the aggressive styles of playing the game - it already works quite well anyways, so I don't think too many decks would remove the Rod and make Brock a staple...
However, Brock does have lots of things going for it. For one thing, by being a Supporter to repeatedly use VS Seeker out, it can make decks that are highly prone to decking out safer to play against Mill decks. It's an excellent endgame utility, particularly for 6-prize based decks, like Greninja Break. If you know that your deck involves extending the length of the game play, or recklessly discards Pokemon and energy, Brock looks like an excellent card to tech in.
From all this... Why not use both the of these cards in a deck? It's like having both Float Stone and Olympia in the same deck to gain better manuvuerability: One is a generic, easy to play item for a single use, while the other is a reusable card for when you really need it.
