This custom set brilliantly unites two nostalgic archetypes into a cohesive Fusion-based strategy with:

• Crystal Beast's resource resilience
• Neo-Spacian's swarming
• HERO's explosive Fusion plays

Key improvements would be:

• A dedicated searcher for "Elemental HERO Neos"
• GY protection for Fusion materials

Overall, a well-designed hybrid package that could revive both archetypes competitively.
