Invasion of Gobakhan // Lightshield Array

Apr 14, 2023 · As a Siege enters the battlefield, its controller chooses an opponent to be its protector.

Apr 14, 2023 · Playing the exiled card follows all normal timing restrictions.

Apr 14, 2023 · A battle can be attacked by all players other than its protector. Notably, this means a Siege’s controller can attack it.

Apr 14, 2023 · If a battle that’s being attacked somehow stops being a battle, it is removed from combat. Similarly, if its controller changes in the middle of combat, it is removed from combat.

Apr 14, 2023 · In a multiplayer game, if the protector of a battle leaves the game and that battle is not currently being attacked, its controller chooses a new protector for it as a state-based action. If it is being attacked, its controller chooses a new protector for it once no creatures are attacking it. This means that it continues to be attacked and can be dealt combat damage as normal.

Apr 14, 2023 · The set of creatures affected by Lightshield Array’s last ability is determined as the ability resolves. Creatures you begin to control later in the turn and noncreature permanents that become creatures later in the turn won’t gain hexproof and indestructible.

Apr 14, 2023 · If a permanent that is represented by a transforming double-faced card becomes a copy of a Siege, it will be exiled as that Siege’s triggered ability resolves, then it will be cast transformed. Note that this applies only to transforming double-faced cards, not to modal double-faced cards that can normally be played using either face.

Apr 14, 2023 · If the exiled card is a modal double-faced card and its back face is a land, its owner may play it as a land. (Note that if the front face is also a land, you couldn’t have exiled it to begin with.)

Apr 14, 2023 · If a Siege never had defense counters on it (perhaps because a permanent became a copy of one), it can’t have its last defense counter removed. It will be put into its owner’s graveyard. You won’t exile it or cast the other face.

Apr 14, 2023 · Battles can’t attack or block, even if one also becomes a creature. If an attacking or blocking creature somehow becomes a battle in addition to being a creature, it is removed from combat.

Apr 14, 2023 · If a battle has no defense counters, and it isn’t the source of a triggered ability that has triggered but not yet left the stack, that battle is put into its owner’s graveyard. This is a state-based action. This doesn’t cause a Siege’s intrinsic triggered ability to trigger.

Apr 14, 2023 · Sieges each have an intrinsic triggered ability. That ability is “When the last defense counter is removed from this permanent, exile it, then you may cast it transformed without paying its mana cost.”
