yugioh guardian deck 2018 Rafael - Sanctuary of the Guardians TCG - Maze of Memories:

Faster Completion By purchasing individual cards, you can quickly fill in the gaps in your collection without having to rely on luck

Special Summon up to 3 non-Rock "Gem" monsters with different names from your Extra Deck and/or GY, ignoring their Summoning Conditions, also you cannot Special Summon monsters from the Extra Deck for the rest of the turn, except Fusion monsters

Continuous self-mill cards mill you multiple times over different turns, like Deranged Assistant and Mesmeric Orb

This has unquestionably made the cards so much more enticing to collect, with far more than a holo sheen to seek

It might be possible if you want to reuse a powerful Continuous Spell like Hysteric Sign
