Why This Set Matters

Mega Gengar ex not only packs strong stats and synergy with Darkness-themed strategies, but its ability to manipulate prize cards introduces a fresh layer of tactical depth.

Mega Diancie ex, while more niche, could still shine in specific builds that lean into damage mitigation or energy-discard mechanics.

As a budget-friendly and feature-rich release, these Mega Battle Decks are prime picks for new and experienced players alike.
