UU Game Terminology - Requirement

A Requirement is a statement that MUST be fulfilled to be able to do something else.

I have a card which states that I must do one thing, then do another. I canâ€™t do the first part of the card. Can I still do the second part? If you can't perform the first action listed on a card, you don't get to perform the second. If you can't perform the first action listed on a card, which is a requirement you cannot play the card.

If I have multiple cards which require targets for their effects, can I select the same target twice?

If multiple triggered effects require a target, the same card may not be selected twice in the same link. If there are not enough cards to target, you may only trigger as many effects as you have options for targets. You must select targets for mandatory effects before selecting targets for optional effects.

	A Requirement for an individual card is contained as the first statement of the card text.			The card effect to Sacrifice 4 unicorn cards occurs if the card resolves (un-neigh'd) (This is the REQUIREMENT). If the Player would be unable to Sacrifice 4 Unicorn Cards the Player cannot Play the card.

	A requirement effect from a card that is already in a Stable or a card played by a Player.		Every time a unicorn card enters or leaves a Stable, the Requirement to Discard a card must resolve (if able). If the unicorn card would be entering the Stable from being played and the Player is unable to Discard a card that Player cannot Play the unicorn card. This is the REQUIREMENT.

	A requirement effect from a card that is already in a Stable or a card played by a Player.		There is NO Requirement to Play the card. If a unicorn card is NOT sacrificed, (This is the REQUIREMENT). The Player would NOT draw a card.

	A requirement effect that is added to other cards.		There is NO Requirement to Play the card. This card creates a Requirement on every Basic Unicorn Card. (This becomes a REQUIREMENT).

CARD EFFECTS WITH MULTIPLE ACTIONS
When a card effect requires multiple actions, those actions are sometimes separated by "and," "then," or "If you do." When resolving card effects, always perform multiple actions in the order in which they are listed on the card.

If a card says "and," you must perform both actions.
If a card says "then," you may only perform the second action if you successfully perform the first action.
If a card says "If you do," only perform the second action if you choose to perform the first action.

ORDER OF RESOLUTION: THE EFFECT CHAIN
Sometimes, the effect of one card triggers the effect of another card. When this happens, each effect is considered its own link in an effect chain. You must resolve the effect of the first link before moving on to the next link in the chain. All links in the chain must resolve before gameplay continues.

There are times when multiple effects may trigger simultaneously, such as during your Beginning of Turn phase. All of these effects are considered to be a single link in the effect chain. Any targets of these effects must be chosen before this link in the effect chain resolves. If any of these effects trigger the effect of another card, another link is added to the effect chain.

If multiple triggered effects require a target, the same card may not be selected twice in the same link. If there are not enough cards to target, you may only trigger as many effects as you have options for targets. You must select targets for mandatory effects before selecting targets for optional effects.

IMPOSSIBLE ACTIONS

If you have a card in your hand that requires you to perform an impossible action, you may not play it. Sometimes, however, the effect of a card in your Stable or a card played by any other player may require you to perform an impossible action. If this situation occurs, disregard that action. Some impossible actions include:
