MTR 4.3 Out-of-Order Sequencing

Due to the complexity of accurately representing a game of Magic, it is acceptable for players to engage in a block of actions that, while technically in an incorrect order, arrive at a legal and clearly understood game state once they are complete.

All actions taken must be legal if they were executed in the correct order, and any opponent can ask the player to do the actions in the correct sequence so that he or she can respond at the appropriate time (at which point players will not be held to any still-pending actions).

An out-of-order sequence must not result in a player prematurely gaining information which could reasonably affect decisions made later in that sequence.

1. A player discards a card to pay for Masticore’s upkeep cost before untapping his or her land.
2. A player resolves Harrow and puts the card into his or her graveyard, then searches.
3. While resolving Restore Balance, a player discards before sacrificing lands and creatures.
4. A player with two creatures being put into the graveyard due to state-based actions resolves the leaves-the-battlefield triggered ability on one of them before putting the other creature in the graveyard.
5. A player declares a blocker, animates a Treetop Village, and then attempts to block with that Treetop Village.
