Youre paying for the experience of opening a 25th anniversary set the Pikachu V-UNION guaranteed hit, the prism foil parallels, and the chance at Mew UR or a high-value promo card
Moving on to Strixhaven (2021), we again find two also-rans and probably the most impactful cards with this mechanic at the time of writing in Card not found
When you have too many cards in your hand, make use of spare Event cards such as "OP11-060 Let's Crash This Wedding!!!" by trashing them for Nami's [On Your Opponent's Attack] effect, similar to a Counter, allowing you to keep your hand size below 7 to activate your Leader effect
Double-sided printing: If you want to print on both sides of the card, ensure your printer supports double-sided printing and adjust the print settings accordingly
If a card is valuable to you, double sleeve it and keep it away from playmats covered in dust or glitter
This card could probably work better as part of the 99 in a few decks, but it can make for a fun, more aggressive aristocrats deck
