Until end of turn, whenever a player taps an Island for mana, that player adds an additional .
Why is this card good?
High Tide is the engine that powers mono-blue and Ux combo/storm decks. For one mana, every Island you tap effectively doubles in value — and with rituals, untap effects, and cantrips chained in a single turn, that snowballs fast into game-ending mana.
This is a dedicated storm/combo card, not a generic ramp spell. It wants commanders like Urza, Lord High Artificer, Talrand, or any high-Island-count blue deck looking to combo off in one explosive turn. It pairs beautifully with untappers (Turnabout, Snap, Frantic Search), cost-reducers, and bounce-lands to generate absurd mana for a Comet Storm, Stroke of Genius, or a Laboratory Maniac/Thassa's Oracle finish.
Don't play it if you're not building around it. It does nothing on its own — no Islands, no payoff, no combo means a dead card. Decks running heavy nonbasic lands, or that just want incremental value, get far more from rocks or dorks. This is a precision tool for cEDH-adjacent storm shells, not casual ramp.

The delayed triggered ability refers to any land with the land type Island, not just those named Island.

The effect applies even if the Island in question entered the battlefield after High Tide resolved.
