Permanent cards are artifact, creature, enchantment, land, and planeswalker cards. Land cards with basic land types have intrinsic activated mana abilities associated with those types.

4/17/2020
Activated abilities contain a colon. They’re generally written “[Cost]: [Effect].” Some keyword abilities are activated abilities (such as cycling) and will have colons in their reminder text.

4/17/2020
An activated mana ability is one that produces mana as it resolves, not one that costs mana to activate.

4/17/2020
Effects that reduce the generic mana cost of an activation cost can’t reduce that cost’s colored mana requirements. The activation cost is reduced by only 1 if doing so reduces that cost to one mana. For example, a cycling cost of 2 would become 1, and one of 1R would become R. The activation cost is unaffected if it already costs one or zero mana (such as the activation cost of Zirda’s last ability).

4/17/2020
Activating Zirda’s last ability after a creature has blocked won’t remove the blocking creature from combat or cause the creature it blocked to become unblocked.

4/17/2020
Your companion begins the game outside the game. In tournament play, this means your sideboard. In casual play, it’s simply a card you own that’s not in your starting deck.

4/17/2020
Before shuffling your deck to become your library, you may reveal one card from outside the game to be your companion if your starting deck meets the requirements of the companion ability. You can’t reveal more than one. It remains revealed outside the game as the game begins.

4/17/2020
The requirements of the companion ability apply only to your starting deck. They do not apply to your sideboard.

4/17/2020
If more than one player wishes to reveal a companion, the starting player does so first, and players proceed in turn order. Once a player has chosen not to reveal a companion, that player can’t change their mind.

4/17/2020
If you reveal a companion outside the game, for as long as it remains there, you may cast it any time it’s legal to cast. Once you do, it comes into the game and behaves like any other card you’ve brought into the game. For example, if it’s countered or destroyed, it’s put into your graveyard, remaining in the game.

4/17/2020
The companion’s other abilities apply only if the creature is on the battlefield. They have no effect while the companion is outside the game.

4/17/2020
The companion ability has no effect if the card is in your starting deck and creates no restriction on putting a card with a companion ability into your starting deck. For example, Zirda may be in your starting deck even if your other permanent cards don’t all have activated abilities.

4/17/2020
You may have one companion in the Commander variant. Your deck, including your commander, must meet its companion requirement. Your companion is not one of your one hundred cards.
