There have been many instances in Pokemon Trading Card Game Pocket where players have found things out the hard way. One player figured out the game had a damage cap mid-battle, while another was barred from opening packs until they'd spent their Pack Points.
It's just a shame about the Dark-type weakness.
Now, another discovery has been made following the release of Space-Time Smackdown that shows Koga and Pokemon Tools are not a good combination.
If you've not dived too much into Pokemon Trading Card Game Pocket since the release of Space-Time Smackdown, Pokemon Tools are a new type of item. When played, they are attached to your Pokemon, providing them with a variety of benefits. Rocky Helmet deals 20 damage to the opposition if it damages your Active Pokemon with an attack, Giant Cape gives your Pokemon 20 extra HP, and Lum Berry cures your Pokemon from any status ailment at the end of your turn. They're valuable tools that can swiftly turn the tide in battle.
Unfortunately, Bocephus-the-goat on Reddit found out that while these tools are great, they don't work well with Koga.
Koga plays its part in a stall deck...
