Today's CotD is Mamoswine GL from RR, a fun card. Statwise, 100 HP is nice for a SP, x2 Weakness to :metal: is ok, -20 Resistance to :lightning helps, and :colorless:colorless:colorless:colorless to Retreat is nasty (though you'll likely just Poke-Turn this guy if he gets into trouble). Icy Aura is a fun Poke-Body, dealing a damage counter to each active Pokemon (namely your opponent's, though yours also if you play the non-existent doubles) if they're not a :water: type between turns; basically, a sorta semi-Poison for free, that's only dependent on Mamoswine GL being active and the opposing Pokemon not a :water: type. Avalanche is pricey at :water::water::colorless:colorless
colorless less with Energy Gain) for 60 and a 50/50 chance of dealing 10 to each of your opponent's Benched Pokemon. Overall, if it weren't for the sub-par attack, this could be a rather competitive card. But alas, it's mainly there for fun.
Modified - 5/10 (Not bad for fun play, but suffers issues in the competitive scene)
Limited - 7/10 (At worst, you set him out there and he's a big wall that deal a continual damage counter inbetween turns. Should you get his attack going, it becomes more fun)
Unlimited - 1/10 (Too slow, not effective)
