For example, the main effect would be "When a monster is Summoned, declares an attack or activates its effect, or a card effect is activated that targets a monster on the field: The controller of that monster rolls a six-sided die and applies the result." Then, some of the results could be: "You can Normal Summon 1 extra monster this turn" (think of a D&D character randomly dragging a friend to a battle with a monster)
Heavy Storm destroys all spell and trap cards on the field when it is activated, which is a nightmare for control decks to deal with because those decks will now not have a way to respond to the opponent's plays
But thankfully, the English-language run of Scarlet & Violet 151 has quite a few solid Mew cards that are far easier to find, including the Mew ex Holofoil and Promo Mew cards released with the set in 2023
Hope you enjoy and can make your own Pokmon theme tree.
You know, as long as they dont sell out before its my turn in the queue.
