Mewoscarada, Giratina Ex, Red, Pokemon Center Lady, and Iono are all worth collecting, but with Darktina decks mostly out of the meta, Giratina Ex is seeing a lot less play, and the supporters are typically played in single copies
I will be discussing combos and more for Witchcrafter, which has become a complete build following the announcement of additional new cards
Theres numerous reasons why Paradox Rift is the best choice right now for competitive players and collectors but the main one is that its the most recent set, with the newest mechanics and keywords
Activate the Effects of cards already on the field
Likewise, Meowth seems like a card purely made for collection purposes, although that could change if a strong Persian card is released in the future
Since the card is currently only being played in just one modern deck, I personally had it in the third spot behind the best blue reactive spells in the format, Counterspell and Force of Negation, but I can see the number one spot going to the best and most efficient threat the color has to offer
