Quick verdict
Strong when your deck can absorb the first 2-Energy cast
Up My Sleeve becomes easier to play after each cast and supplies several attacks at once. It needs enough hand space and benefits most from decks that reward Shivs, repeated attacks, or cheap-card volume.

How to evaluate it
Judge Up My Sleeve by the job it fills in your current deck, the fights ahead, and whether its 2 energy competes with a more urgent play. A card being uncommon does not make it an automatic pick. Check its class guides and the current patch notes before treating any single-card rating as universal.

How the cost reduction changes the card
The first copy begins at 2 Energy, so the opening cast is the real test. After it resolves, its cost falls by 1 for the rest of combat. A second cast is easier to fit into a normal turn, while repeated access can turn it into efficient card volume.
Do not count only the later ceiling. If your deck cannot safely spend 2 Energy on the first cast, the card may sit in hand during the turns that decide the fight.
Upgrade and hand-space checklist
The upgrade increases the generated Shivs from three to four. That is meaningful when every Shiv triggers extra value, but it also makes hand space more important.
- Leave enough empty hand slots before playing it.
- Prioritize the upgrade when one additional Shiv triggers meaningful damage or utility.
- Be cautious when draw-heavy turns already approach the hand limit.
