A self-contained loop card that grants 2 diamonds and returns to the top of the draw pile every time you use it. For 1 Energy you get 8-11 damage plus 2 diamonds, which is extremely efficient. You cannot spam it multiple times in a single turn, but the guarantee that you draw it every turn is a huge strength.

Combined with Radiant Flood (damage scales with diamonds gained), one card earns both single-target and AoE damage. As one of the best reliable diamond engines in the class, it fits in essentially every diamond-oriented deck.

• Play it early each turn to lock in 2 diamonds for your other diamond-consuming cards.
• Stockpile diamonds with Shining Strike before casting Radiant Flood the same turn to maximize damage.
• Because it returns to the top, cards like Photon Cutter or Shimmer can deliberately push it back into the pile so you can draw other cards.

• Radiant Flood: Gain 2 diamonds with Shining Strike first, then Flood hits ALL enemies for 8-10 extra damage.
• Black Hole: Every diamond gain from Shining Strike deals AoE damage. A steady source of passive damage every turn.
• Starchild: Each 2-diamond gain converts into 4-6 Block, giving offense and defense in one card.
• Photon Cutter: Lets you intentionally bury Shining Strike from the top of the pile to draw something else.

• Regent Star / Diamond Stack (Key card) (S Tier)
