Description
This Japanese-exclusive set is an absolute icon, famous for one of the most sought-after chase cards in the entire Scarlet & Violet era

Once per turn, when creatures with counters on them deal combat damage to a player, the player who controls Tidus can draw a card and proliferate (i.e., add an extra counter to creatures and permanents that already have them)

The set has grown tremendously both in monetary and historic value

So, a quick analysis: for 1 mana, you can put this card into play, and it can be tapped to gain CC (two colorless mana)
