Thanks to PokeDan23 from our forums, we now have all of Dragon Vault 's card scans
While we love the art, we're not so sure about the strength of the card itself
The sound waves that their voices and instruments create totally cripple the Chosen Children's partner Digimon, but as Izumi Koshiro theorizes, they also trigger the irregular evolution of Tachikawa Mimi's Palmon into Ponchomon, who cancels out their sound waves with her own rhythm and defeats both of them
Sparking your draw power into life, the Electric-type Pokmon can use its ability, Instant Charge, to let you draw three cards once per turn
There are also ways to bank a board wipe for later
Before doing anything like swapping Ajani for an Elspeth or Woe Reaper for an Inspector or anything like that I would look to simply replace Lone Missionary and Lone Rider
