Upgraded

• Cost: 1 (spend 2 diamonds)
• Effect: Deal 13 damage. Next turn, draw 3 cards.

An excellent card that attacks while boosting next turn's draw. Combined 1 Energy + 2 diamonds feels a touch heavy, but 12-13 damage plus +2 or +3 draw on the next turn is a great deal. Strengthening next turn's hand makes combo setups far easier.

Upgraded Draw 3 is especially strong — cast it the turn before a big combo turn to secure a stacked hand. Worth running in any deck with reliable diamond supply.

• Cast it the turn before a big play (Comet, Seven Stars, Consolidate combo, etc.)
• Requires 2 diamonds, so generate them first with Awe, Radiance, or Solar Strike
• Upgraded Draw 3 is great per-turn value. Prioritize upgrading it

• Consolidate: Retains the full hand next turn + more cost. Guiding Star's draw boost turns into a massive combo hand
• Genesis: 2-3 start-of-turn diamonds cover Guiding Star's cost consistently
• Pale Blue Dot: Combines with the next-turn draw to pull even more cards

• Regent Star Diamond Stack (S Tier)
• Regent Resource Explosion (Key card) (A Tier)
