Rating & Analysis
Space Joker has a 1/4 chance per played hand to permanently level up that hand by 1. At Uncommon $5, ~25% trigger expectancy per hand makes it a long-term scaling Joker. Over 20 hands, expect ~5 level-ups — a Flush (+35 Chips ×4 Mult base) grows to +85 Chips ×9 Mult.
The dream pairing is single-hand-axis builds (Flush / Straight / Full House) where every hand is the same type. Oops! All 6s (all probabilities ×2 → 1/2) doubles trigger rate; Oops + Space Joker = 1-in-2 hand level-ups, exploding growth.
Blueprint / Brainstorm copies have independent rolls, effectively doubling probability. Constellation (Tarot use → suit level +1) / Burnt Joker (Planet use +Mult/+Chips) parallel for hand-level scaling. Tier lists rate A overall, A+ with Oops! All 6s / single-hand axes. $5 for permanent hand growth is theft — buy on sight.

Tips & Usage
- Lock into one hand type for compounding growth.
- Oops! All 6s doubles trigger rate — mandatory pairing.
- Blueprint to its right gives independent rolls.
- Buy early; long-term scaling pays off late game.
- Pair with Black Hole (all hands +1 level) for hand-level axis dominance.
Caveats
- Probability-based — trigger count varies with luck.
- Avoid Perishable — expiry costs growth opportunities.
- Eternal Space Joker is fine — value compounds over time.
- Permanent +1 hand level is locked in, but switching builds reduces value.
- 1/4 base rate is low — Oops! pairing is near-mandatory.
