Battle — Siege // Legendary Creature — Serpent
wotc · 2024-01-12
You can tap any untapped creature you control to convoke a spell, even one you haven't controlled continuously since the beginning of your most recent turn.
wotc · 2024-01-12
Tapping an untapped creature that's attacking or blocking to convoke a spell won't cause that creature to stop attacking or blocking.
wotc · 2024-01-12
When calculating a spell's total cost, include any alternative costs, additional costs, or anything else that increases or reduces the cost to cast the spell. Convoke applies after the total cost is calculated. Convoke doesn't change a spell's mana cost or mana value.
wotc · 2024-01-12
If a creature you control has a mana ability with {T} in the cost, activating that ability while casting a spell with convoke will result in the creature being tapped before you pay the spell's costs. You won't be able to tap it again for convoke. Similarly, if you sacrifice a creature to activate a mana ability while casting a spell with convoke, that creature won't be on the battlefield when you pay the spell's costs, so you won't be able to tap it for convoke.
wotc · 2024-01-12
Because convoke isn't an alternative cost, it can be used in conjunction with alternative costs.
wotc · 2024-01-12
Tapping a multicolored creature using convoke will pay for {1} or one mana of your choice of any of that creature's colors.

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.
wotc · 2023-04-14
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
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.
wotc · 2023-04-14
If you sacrifice Caetus while casting a noncreature spell (say, to activate a mana ability), the spell won't have convoke when you pay its costs unless it has convoke some other way.
