Shadowborn ApostleHow it works & interactions with other cards

Breaking the Four-Copy Rule

The first ability of Shadowborn Apostle is a static effect that functions during deck construction. It allows you to ignore the limit of four copies per deck in any format where the card is legal. Note that this does not bypass format legality; if the card is banned in a specific format, you still cannot play it. However, in formats like Commander or Legacy, you can play twenty, thirty, or even more copies to ensure you always have enough ritualists on the battlefield.

The Demonic Ritual

To activate the Apostle's ability, you must pay one black mana and sacrifice six creatures named Shadowborn Apostle. This sacrifice is part of the activation cost, meaning the creatures are moved to the graveyard immediately as you put the ability on the stack. Your opponents cannot respond to the sacrifice itself to try and kill one of the Apostles to stop the activation. Once the cost is paid, the ability sits on the stack waiting to resolve.

Resolving the Search

When the ability resolves, you search your library for any creature card with the subtype 'Demon'. You put that card directly onto the battlefield. This is not a 'casting' action, so it cannot be countered by spells like Negate, and it bypasses the mana cost of the Demon. After the Demon enters the battlefield, you must shuffle your library. If you cannot find a Demon or choose not to, you still shuffle.

Strategic Considerations

One common mistake is assuming the Apostle whose ability you activate must be one of the six sacrificed. This is false; you can sacrifice any six creatures named Shadowborn Apostle you control. As long as you have a seventh Apostle or another way to pay the black mana, you can keep the 'leader' on the board. Additionally, because the sacrifice happens all at once, 'death triggers' from other permanents will see all six creatures hitting the graveyard simultaneously.

Interaction examples

Draining Life with Blood Artist

Blood Artist

If you have Blood Artist on the battlefield when you activate the ability of a Shadowborn Apostle, its ability will trigger six times. Since the cost of the Apostle involves sacrificing six creatures, Blood Artist sees each one die. You will choose targets for those six triggers, resulting in a total of 6 life gained for you and 6 life lost for your opponents, all before your Demon even enters the battlefield.

Fixing Mana with Ornithopter of Paradise

Ornithopter of Paradise

To activate the Shadowborn Apostle, you need one black mana. If your lands are tapped or you lack a black source, you can tap Ornithopter of Paradise to add {B} to your mana pool. This satisfies the mana requirement of the activation cost. Note that while Ornithopter of Paradise is a creature, it is not named 'Shadowborn Apostle', so it cannot be one of the six creatures sacrificed to pay the cost of the search ability.
