Flip

Flip means turning a face-down card on the battlefield face up, thereby summoning it.

This is the order of operations to follow:

• reveal the card to both players
• choose to activate Shadowwalker, and resolve it before continuing
• chose the desired orientation
• physically flip the card and put it back on its zone on the chosen orientation
• activate any "When flipped" effects
• collect Mana Counters on the card if it has any Knowledge
• activated any "When summoned" effects

Different card types have different flipping requirements:

• Monuments can never be face-down, and thus can never be flipped.
• Both artifacts and creatures must be flipped when they are targeted (either by attacks or effects).
• Artifacts can be proactively flipped at instant speed, in fact, even as part of activating one of its effects.
• Creatures can only be flipped when targeted by an effect or attack.
