Strategy
Blue-primary, green-splash tempo built on the “draw your second card each turn” payoffs. A 1-drop cantrip shell (Opt, Spyglass Siren, Spectral Sailor) plus Clue tokens and Chart a Course reliably triggers a SECOND draw every turn, which is the deck’s whole engine: Otter-Penguin turns unblockable for the turn, Knowledge Seeker and Tiger-Seal grow/untap, and Mischievous Mystic spits out flying Faeries. Brineborn Cutthroat plus Spectral Sailor’s flash means you hold up Essence Scatter / Negate on the opponent’s turn and still develop, casting Opt or a bounce spell on their turn to pump Cutthroat AND tick the second-card payoffs. Enduring Curiosity and Tatyova convert combat hits and land drops into a grinding card lead; Kiora refills outright and threatens an 8/8 Scion. Exclusion Mage, Boomerang Basics and Rocky Rebuke supply the tempo interaction the original list was thin on — UB-control instincts ported into Simic, with green doing only ramp/fixing (Breeding Pool, Dreamroot Cascade) and a fight effect.
Upgrade path
Owned-only, zero rare/mythic SPELL crafts. Owned rares used as spells: Enduring Curiosity (own4), Kiora the Rising Tide (own2), Tiger-Seal (own2) — all already owned, no crafts. Breeding Pool is the single approved branch-out shock and the only unowned card, kept at the 1 copy the prior list ran. Refinement vs the prior build: the second-card engine was under-fueled, so I added Opt x2 and Spyglass Siren x1 (own4 common/uncommon) as cheap instant-speed enablers that trigger the payoffs every turn and double as Brineborn fuel, and added Tiger-Seal x1 (OWNED rare, no craft) as an on-theme untapping 1-drop. Swapped the clunky Forecasting Fortune Teller / Mischievous-only redundancy for Exclusion Mage x2 (repeatable bounce on a body) to firm up tempo. Manabase shape unchanged (shock + Dreamroot + owned taplands + basics); a 2nd Breeding Pool would be the only further upgrade and costs a rare craft, so it’s held back.
