About this card
This Supporter works from the wrong end of the deck: look at the bottom four cards, take two of them into your hand, and slide the rest back underneath in whatever order suits you. Its Japanese name reads as an underground exploration party, which is where the lamp and the field kit in the picture come from. Champion Road is built almost entirely out of modernised reprints of older cards, and this one goes back to Skyridge.
