Rimuru strategy
Blue Rimuru in That Time I Got Reincarnated As A Slime is the raid face this page is about. TCG Contender files it as a midrange list, Standard tier 2. This site is hosting 73 public 50-card lists, including 7 recent top 8s. The tier list has Rimuru in A.
How the raid face works
The printed trigger on Rimuru (UE20BT/TSK-1-107) is: [Raid] Add this card to your hand, or if you have the required energy, perform Raid with it. Raid printings in the current 50: Rimuru (UE20BT/TSK-1-107) and Soei (UE20BT/TSK-1-060). In Union Arena, [Raid] lets you add the card to your hand or perform Raid if the energy is there. The expensive copy is the ceiling. The cheaper copies with the same name are the steps. Contender's snapshot calls out that deep redundancy across five Rimuru printings (017, P-001, 107, 053, 052, 050) means the deck rarely whiffs on its central character across a long tournament day. The same snapshot flags that against Tier 1 aggro decks like Sakamoto Days - Shin Asakura or Rurouni Kenshin - Hajime Saito, the midrange curve can fall behind before the Rimuru package comes online.
The current 50-card core
Four-ofs: Feast (UE20BT/TSK-1-062), Gobta (UE20BT/TSK-1-040), Rimuru (UE20BT/TSK-2-017), Rimuru (UE20BT/TSK-1-107), Soei (UE20BT/TSK-1-059), Soei (UE20BT/TSK-1-060), Report (UE20BT/TSK-2-024), and Rimuru (UE20BT/TSK-P-001). Three-ofs: Rimuru (UE20BT/TSK-1-050), Rimuru (UE20BT/TSK-1-052), Rimuru (UE20BT/TSK-1-053), Soei (UE20BT/TSK-1-058), Mystic Thread Strike (UE20BT/TSK-1-065), and Shizu (UE20BT/TSK-P-002). That average is taken from the featured list on That Time I Got Reincarnated As A Slime - Rimuru, then checked against the 73 hosted files.
The curve
Energy 0-2. Gobta (UE20BT/TSK-1-040), Rimuru (UE20BT/TSK-2-017), Rimuru (UE20BT/TSK-1-050), Soei (UE20BT/TSK-1-058), and Report (UE20BT/TSK-2-024) keep the early turns honest. Energy 3-4. Feast (UE20BT/TSK-1-062), Rimuru (UE20BT/TSK-1-107), Soei (UE20BT/TSK-1-059), Soei (UE20BT/TSK-1-060), Rimuru (UE20BT/TSK-1-052), and Rimuru (UE20BT/TSK-1-053) are the mid-curve bodies. This is read off the hosted 50, not a hidden playbook. If your locals file plays a different 3-of, trust that file.
Mulligan
Keep a Raid Rimuru, at least one 0-2 cost setup card, and one Feast (062) if the cheap card missed. Ship a hand of only 7+ cost finishers. That is inferred from costs in the hosted list, not a coach sheet from a hidden room.
Tech and flex
Shizu (UE20BT/TSK-P-002) is the 3-of most lists will argue about.
