Murganda II: Mechanics

Lurk: At any time you could cast a sorcery, you may exile this card face-down lurking under a land you control. Only one card can lurk under a land at a time. You may turn this card face-up and put it onto the battlefield at any time by sacrificing the land its lurking under and paying its lurk cost. Used on 2 cards: Water Boa, Mire Cutthroat

This is a mechanic used to represent creatures hiding in lands.

Revive: PARAM1, remove X +1/+1 counters from among creatures you control, where X is this card's CMC: Return that card from your graveyard to the battlefield. Used on 1 cards: Solemn Wanderer

This is a mechanic used to represent creatures calling the spirits of their dead allies to the battlefield.

In card text or details pages, write the mechanic's code name (playtest name) between square brackets, like "[Crittercast]", "[Bushido 1]" or "[Delay 4 {2}{R}{R}]". It will be expanded to the mechanic's name plus reminder text, such as "Suspend 4 – {2} {r} {r} . (Rather than cast this spell from your hand,...)"
To expand a mechanic's name but not its reminder text, include parentheses at the end of the square brackets: "[Crittercast()]", "[Delay 9 {R}()]".
