I mean, depending on the ruleset & mana cap it's very possible to beat...you just need to get a little creative. That duo is definitely a pain in the ass if you find yourself lined up against it, but there's only so many different combinations of battle settings/rulesets that could even make it a (constant) threat in the first place...at most, maybe you'll run into those two together one in every 10 matches - and that's assuming you're matched up against people who are all doing that same lineup for some reason...
