280 is a very good breakpoint, allowing you to two-shot several popular Pokemon in PTCGL expanded like Regidrago VSTAR (Silver Tempest), N's Zoroark ex (Journey Together), Pidgeot ex (Obsidian Flames), Lugia VSTAR (Silver Tempest), Arceus VSTAR (Brilliant Stars), and Arceus & Dialga & Palkia-GX (Cosmic Eclipse)
If we look at a deck, meaning, a fully 60-cards build, clear strategy that always has had the same attackers, same support Pokmon and same style of play, then Mew is definitely a deck that cannot be compared
The Mythical Island expansion brings over 80 new cards to the game, including five EX cards and five Trainer cards
Tips: Herald of Slaanesh is the absolute best card to draw early
Even unlimited versions of holo cards can fetch a high price depending on which set the item is from
