Today's new CotDs are The New Fossils Fossil (Plume and Cover) from NV...and they stink. I'm actually surprised in ways, as they managed to make an already bad mechanic even worse :nonono:
So unlike what we're used to from before, you no longer count them as Basics or anything; instead, you play them and pray in your top 7 cards lies the correct Pokemon for the Trainer (Tirtouga for Cover, Archen for Plume), which allows you to play them onto your bench. And of course, if you don't hit them, well you've just wasted a Trainer. So really, as bad as the old method was of having to protect a frail Pokemon on the bench (assuming you weren't Trainer locked), at least you could still Candy them into the right Stage 2 for immediate results; instead, you're now forced into even more RNG just to get the basic Stage 1 form out. And it is a shame, as Archeops and Carracosta aren't that bad in of it themselves, it's just the lame mechanic that you have to go through to get them out makes them undesirable.
Modified - 1/10 (Sure I'll let you pay me to use Fossil Pokemon, but I wouldn't willingly use them otherwise)
Limited - 1/10 (Roflmao, good luck every hitting one, even with a thinner deck odds are you might have a 2-1-1 line, so good luck getting it to work)
Unlimited - 1/10 (No use here, not to mention none of the Pokemon they turn into are good here anyways)
