2 Level 4 Dinosaur-Type monstersWell then, as if we didn't need another reason to make Rescue Rabbit broke, enter Dolkka. Granted, it's got an amazing effect. Being able to stop monster effects is no laughing matter, especially since there's no "once per turn" clause on the effect. Combined with Laggia, you got yourself one heck of a controlled field. Being able to compensate for Laggia's only weakness has turned this into a very dangerous card, so make sure to eliminate it with a counter trap if you can, especially since Laggia can't respond to counters.
When an Effect Monster's effect activates: You can detach 1 Xyz Material from this card; negate the activation and destroy it.
On a more fun note, Jurracs are going to be a much better deck with Dolkka and Laggia available. Well, that is, if they can be afforded (I assume they will cost a lot). Jurracs perhaps might be able to be a stronger deck in the competitive scene (perhaps at a local level, at least) and are going to be a more welcome alternative than decks focused on Rabbit. However, the hefty price will still affect it.
Either way, Evolzar Dolkka has turned into quite the force and has already made an impact before release. Only time will tell if it will live up to the hype or just show up every now and then. I'm just glad it's restricted to only dinosaurs, otherwise this would be a very big reason to just rage.
