, Plaza of Heroes supports legendary-heavy decks with several distinct mana options. It can produce colorless, any color restricted to casting a legendary spell, or a color represented among legendary permanents you control. Those modes have different requirements, so the land’s useful colors can change as the battlefield develops.
Its defensive activation costs three mana, taps and exiles Plaza, and grants a target legendary creature hexproof and indestructible for the turn. That can protect a commander from targeted removal or destruction, but it consumes the land. The unrestricted colored mode depends on an actual legendary permanent’s colors, while the legendary-spell mode can help cast the first legend before that board exists.
Choose interaction around the threat it actually addresses. Targeted removal, destruction, exile, and abilities on the stack require different answers, so no single protection slot covers every exchange. Leave the relevant mana available before committing to a threat, and identify whether the important resource is one creature, an entire board, or the spell that must resolve during the current turn.
The defensive ability can target a legendary creature even when it is not your commander. Hexproof and indestructible cover targeting and destruction, but they do not prevent every exile or sacrifice effect. Keep the three-mana payment available before relying on the protection, since Plaza itself must tap and be exiled as part of activating it.
