Other notable cards with Mr Grizz: If you put Pearl down sideways, Mr Grizz can fill and close the gap above for a free special, very solid main street opener. Slosher can safely double activate on the bottom left of pearl too. Order dualies: Not an amazing combo but a double activation that works in a pinch. Kraken also activates with it but I've never used it with Mr grizz in practice, it might be an okay backup opener card, I just use it with zipcaster since it works better offensively.
