in a recent game i had Breena out and a way to draw me a card every time i put one or more counters on a creature. I was amazed how eagerly my opponents did my bidding and rushed to attack each other, getting their lifetotals nice and low into killing range for my buffed creatures - even though i got a whole card and 2 counters out of it each time.

Yet when i play retard Rocco, the card my opponents get by just providing me a single counter and a food token is just too steep a price to even worth considering.
curious
you should run Breena if you can, even if she is unrelated to your gameplan. its almost better than a Ghostly Prison
