[Main] Trash up to 3 cards in your hand. For each
card trashed by this effect, <De-Digivolve 1> 1 of
your opponent's Digimon. (Trash 1 card from the top
of one of your opponent's Digimon. If it has no
digivolution cards, or becomes a level 3 Digimon,
you can't trash any more cards.) Then, delete 1 of
your opponent’s level 4 or lower Digimon.
