What a terrible effect, though
Sure, each half costs one mana more than the split half, but you can add in interaction in your creature spots or a creature in your interaction slot and then a beater later to close out the game, and you can get both effects for one card
Via the Daisuki Pokmon Fan Club, this card was offered as a prize for members who accumulated enough points in the club by attending various meetups and participating in club activities
Judge explains the investment theory: Supply is fixed (Pokmon isnt reprinting old cards), demand keeps growing (the nostalgic Millennial buyer pool isnt getting smaller), and conditions matter enormously (a professionally graded, pristine card can be worth 10 to 100 times more than the same card in rough shape)
The split-second ability makes it just about impossible to counter and renders other players unable to respond as long as its on the stack
