Strengths
* Swarming potential: Crystal Beasts can quickly swarm the field with monsters, making it difficult for your opponent to deal with all of them. This swarming ability is especially useful against decks that rely on monster effects or Spells/Traps that target specific monsters.
* Protection effects: Crystal Beasts have several cards that can protect themselves from being destroyed or targeted by your opponent's effects. This protection makes them very resilient and allows them to stay on the field for extended periods.
* Variety of effects: Crystal Beasts have a wide range of effects that can be used to disrupt your opponent's plays or set up powerful combos. For example, some Crystal Beasts can negate monster effects, while others can Special Summon themselves from the Graveyard or banish your opponent's cards.
Weaknesses
* Reliance on the Normal Summon: Crystal Beasts rely heavily on their Normal Summon to get their plays started. This can make them vulnerable to decks that can disrupt the Normal Summon, such as decks that run cards like "Solemn Strike" or "Dimensional Prison".
* Lack of an inherent boss monster: Crystal Beasts don't have a specific boss monster that can easily take down your opponent. This means that they can sometimes struggle against decks with powerful boss monsters or OTK strategies.
* Vulnerability to backrow removal: Crystal Beasts rely on their Spells/Traps to support their monsters and disrupt your opponent's plays. This means that they can be vulnerable to decks that run cards like "Mystical Space Typhoon" or "Harpie's Feather Duster".
Conclusion
Crystal Beast decks can be a fun and rewarding archetype to play in Yu-Gi-Oh! Duel Links. They offer a unique playstyle that emphasizes swarming the field with monsters and utilizing their various effects to disrupt your opponent's plays or set up powerful combos. However, they do have some weaknesses, such as their reliance on the Normal Summon and vulnerability to backrow removal, so it's important to build your deck carefully to mitigate these weaknesses.
