Thriving IsleHow it works & interactions with other cards

What It Does

Thriving Isle is a non-basic land that enters the battlefield tapped, meaning you cannot use it the turn you play it under normal circumstances. Its primary strength lies in its 'as it enters' ability, which allows you to pick any color of mana except for Blue. Once on the battlefield, it can be tapped for either Blue mana or the specific color you chose when it arrived.

How It Resolves Step by Step

First, as you play Thriving Isle, you must choose a color (White, Black, Red, or Green). This choice happens as the land is entering, so it does not use the stack and cannot be responded to. Second, the land is placed onto the battlefield in the tapped position. Finally, once it is untapped during your next untap step, you gain access to a permanent source of two different mana types for the rest of the game.

Common Mistakes

A frequent error is trying to choose Blue as the secondary color; the card explicitly states you must choose a color other than Blue. Additionally, players sometimes forget that the choice is linked to that specific permanent. If Thriving Isle is returned to your hand and replayed, or if it is blinked, you must choose a color again, and it will enter the battlefield tapped once more.

When to Play It

This land is best played early in the game when you can afford the tempo loss of a tapped land. It is especially useful in Limited formats or Commander, where having access to a specific splash color is vital for casting your spells on curve.

Interaction examples

Fixing Your Colors

If you are playing a Blue and Red deck but haven't drawn any Mountains, you can play Thriving Isle and choose Red. Now, this single land provides both colors you need for the rest of the match.

Synergy with Mana Producers

Command Tower

While Thriving Isle provides a fixed choice of two colors, pairing it with Command Tower ensures that your mana base is robust. Command Tower provides any color in your Commander's identity, while Thriving Isle fills in the specific gaps for your secondary or tertiary colors.

Interacting with Opponents

Exotic Orchard

If you control a Thriving Isle for which you chose Green, and an opponent controls Exotic Orchard, that opponent can now tap their Exotic Orchard for Green mana. This is because Thriving Isle is a land you control that can produce Green mana.
