Battle — Siege // Creature — Dragon
wotc · 2023-04-14
As a Siege enters the battlefield, its controller chooses an opponent to be its protector.
wotc · 2023-04-14
A Siege’s controller can’t be its protector. If a Siege’s protector ever gains control of it, they choose a new player to be its protector. This is a state-based action.
wotc · 2023-04-14
If a non-battle permanent that is already on the battlefield become a copy of a Siege, its controller chooses one of their opponents to be that battle’s protector. However, it will most likely be put into its owner’s graveyard because it has no defense counters (see below).
wotc · 2023-04-14
A battle’s “defense” is displayed in the bottom right corner of the card. A battle enters the battlefield with that number of defense counters. If another permanent enters the battlefield as a copy of a battle, it also enters with that number of defense counters.

Only creatures controlled by a battle’s protector can block creatures that are attacking that battle. This means a Siege’s controller can never assign creatures to block for it.

A battle can be dealt damage and be target of spells and/or abilities that target “any target.”
wotc · 2023-04-14
Damage dealt to a battle causes that many defense counters to be removed from it.
wotc · 2023-04-14
A battle can be attacked by all players other than its protector. Notably, this means a Siege’s controller can attack it.
wotc · 2023-04-14
Invasion of Tarkir’s enters-the-battlefield ability triggers and goes on the stack without a target. As it resolves, you’ll reveal any number of Dragon cards from your hand. As the card reminds you, that number can be zero. Then the second “reflexive” triggered ability will trigger. You’ll choose the target for that second ability at that time.
wotc · 2023-04-14
If you don’t reveal any Dragon cards from your hand, the reflexive triggered ability will cause Invasion of Tarkir to deal 2 damage to the target of the ability.
wotc · 2023-04-14
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.”
wotc · 2023-04-14
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.
